You should definitely put them somewhere. But be sure to retain the
original text too, so we can go back and compare if we need to later.

Helping with Stegotorus should count as working on an http transport, yes?
There are still a lot of barriers to having a good http transport, but
I think the prize is worthwhile enough that we should keep working to
reduce the number of barriers.

I think it would be worthwhile to explore how much of a mess it would
be to use DNS as a transport in practice. Does the bridge side need
to run a hacked nameserver on port 53? That sounds like a deployment
problem for some bridge operators (but not for others). More generally,
this topic like a great task to write up as a research problem for some
student to tackle.

For our "one more", we're already looking into pretending to be Skype
video as a transport (Skypemorph). It would be great to put some effort
into the deployment side of Skypemorph -- better READMEs, identify and
start fixing Tor issues like #5483, etc.

All of that said, I totally agree that for #1, we need to be sure Andrew
and the funder both understand that we can't promise that we'll deploy
any particular transport protocol -- the first step is research, and
that means step two must stay flexible.

Sounds great. We should be sure to generalize what we do with obfsproxy
and metrics.tp.o, so it will be smoother to do for our next pluggable
transports (e.g. the ones we mention in #1 above). I think from #5040
and friends that it looks like this is already the plan?

Is "extended OR protocol" api support part of the planned python library
that Blanu and George are working on? If not, we should get it on
somebody's list.

Ok.

I'd like to see that happen too.

We might also choose to say that "bridgedb remains running the whole time"
is a prerequisite for finishing deliverable 4.

Not really. In the research world, it is totally normal to 1) do X, 2)
ask for money to do X, 3) spend that money to do Y, 4) ask for money to
do Y, rinse/repeat. It's the only sane way to do long-term research on
predictable timelines. Or said another way, I think nobody will mind that
we've made great progress on the deliverable already, given that there's
plenty more work to do on the topic.

That said, now would be a great time to brainstorm some SponsorZ-style
items we'd like to do on this topic next, and plan to get those started
too (i.e. do the above step 3). The first thing that comes to mind is
having bridgedb know when some of its bridge addresses are blocked in
some countries.

We should involve Karen in this discussion, since she's already doing some
sample videos, and she's a plausible fit for parts of the "tech writer"
role we describe. The question for Karen is how much of a distraction
it will be for her relative to her fundraising work.

We should figure out what Runa had in mind by "partner", and how much
of that we can do ourselves; there is currently no money in the 2012
budget for said partner.

Andrew is hoping to use this as an opportunity to explore "hire people who
will do great work and not charge American prices". Apparently our current
Farsi translator is one such person, and Andrew hopes we find more.

We have four separate directions in mind for this "community manager"
notion (not all funded by SponsorL, mind you):
1) Relay operator coordinator. Somebody to keep relay operators happy
and in touch with us, encourage people to set up new relays, organize
recommended configurations, etc. Especially important in tandem with our
"network diversity" work at #6232.
2) Volunteer-developer coordinator. Somebody to take incoming volunteers
and help them find good existing projects to work on. Likely involves
making our volunteer page more usable. Should also include knowing enough
about every project to recognize and identify good low-hanging fruit,
and knowing enough about our priorities to make smart decisions.
3) Blog/forum/mailinglist coordinator, to make sure our users have useful
answers, and ultimately to manage and organize the volunteers who make
sure our users have useful answers.
4) Social media person, to be our face on twitter, etc.

I believe the plan is for Runa to cover #4, and for us to contract
somebody in our relay operator community part-time for #1 to start. I
think there is no plan for #2 and #3 yet; but I'd love it if we could
get somebody part-time for #2.

Countries like Venezuela are likely to be on more peoples' radar in
the coming years. As for French, a lot of North Africa can do French
better than they can do English. I bet that's at least partly the case
in Vietnam too.

There's totally time to write 'Arabic' into the list if we want. Note
that just because we promise more languages doesn't mean we get any more
money though.

Here's a list of languages the funder thought we might want to put on
the contract: "Arabic, Farsi, Mandarin, Vietnamese, Burmese, Spanish".

One phrasing of this deliverable I've seen is "fix top 15
torbutton/torbrowser bugs as seen in ticket system". Mike wants somebody
who can jump into the Firefox code and bend it to our will. He posted
a job description at
https://www.torproject.org/about/jobs-browserhacker.html.en
and is waiting on Andrew and tor-exec to say "yes you can announce and
start interviewing". See other thread responses.

I believe there's no funding specifically for Thandy work other than
this upcoming SponsorL contract. So I would guess Sebastian's Q3 work
was going to be this deliverable 9.

Ok. This work does tie into SponsorJ's hopes that we'll be able to
automate builds for our bundles -- Thandy deployment without buildbot
and easy automated build and QA will leave us pretty frustrated. Maybe
that's what Sebastian meant when he talked about Q3 above.

We should also involve Nick in the discussion for deliverable 9, since
it's going to need bugfixes/etc on the Thandy code. And Tomas from the
Vidalia side.

I think what we have in mind here is a harness for running TBB on a
given OS in a VM, having it do some stuff, and then having an automated
way to see what changed on the system.

I think the funder would be satisfied if we hack together something to
do the comparison once per OS, and then write a report categorizing the
traces and describing what can be done about each.

But imo that would be a waste of the time/money, since it would cost the
same amount of time and money to do it a second time. Instead we should
focus on building a framework for running TBB and automatically noticing
regressions -- whether that's new traces left behind, or anonymity leaks
when you do a websocket query, or whatever. This topic clearly ties into
the "QA automation" topic.
