Hi George, thanks for the reply.

I'd like to see human-readable names in HSes, but I'm not very

this, but I'm not sure if I would be a good mentor for this.
Any idea who might be a good mentor for this idea?
BTW, I remember watching a presentation about namecoin, and it seemed
like there are still a few serious unresolved problems (domain
squatting is easy, no revocation, lightweight clients are
impossible).
Domain squatting is known to be an issue, and there are proposals to
adjust the name pricing structure of Namecoin to disincentivise
squatting. While these proposals are not implemented at the moment, I
think it's likely that they will be implemented in the future.
There is a workaround (recently implemented) for a specific use case of
revocation: a Namecoin name can import data from a second Namecoin name,
in such a way that one name can be held in a safe location while the
other name would be easier to update (but overrideable by the first
name). So if the easy-to-update name has its keys compromised, the
safely-stored name can recover the situation. This doesn't solve the
more generic revocation problem; I will inquire with the Namecoin
developers about this. (I think it's possible to add full revocation
support to Namecoin in the future.)
Lite clients do not exist right now, but are definitely possible to
build. The UTXO lite client being implemented for Bitcoin should be
mergeable to Namecoin in the future.
Also, namecoin are not anonymous, but people who get HS
domain names care about anonymity.
You are correct that Namecoin addresses are linkable. I think it's
likely that Zerocoin or CoinJoin will be implemented for Namecoin in the
future, which would solve the issue. In the meantime, I think the best
way to get mostly-anonymous namecoins would be to obtain bitcoins, run
them through a mixer, and use the resulting anonymized bitcoins to
purchase namecoins on an exchange. (Most exchanges don't ask for
identification unless you're using government-issued currency.) I think
some exchanges block Tor, so it might be necessary to use a proxy or VPN
between Tor and the exchange.
Yes, you seem like a good match for this project.
Familiriaty with YaCy will be very useful indeed.
On the crawler side, may I suggest you to also look into archive.org's
Heritrix crawler? Someone told me that it's what the cool kids use
these days for crawling the web but I haven't used it myself.
Thanks for the tip, I will look into Heritrix.
I think you would be a good candidate for this project. However, be
warned that it's likely that more good candidates will apply for this
project so it might be a tough competition.
Is there a way that I could submit two proposals (one for each of the
projects I listed), so that if there's tough competition for one project
I can still be considered for the other? Or does GSoC only permit one
proposal per student per organization?
Thanks,
-Jeremy Rand
