Yep, I agree.

Well, bridge by default is what they B3's are set up with. I also
figure that a bridge sees less traffic than a relay, and so it might
be more "friendly" for new users. But I like the idea of having a
bunch of common configs, and we can also suggest bandwidth limits.

Maaaaybe. I haven't tried, but it can't be that hard. I'll look into it.

Works for me. It's great to get feedback that will help get me started.

Good question. I love Debian, but I'm sure Ubuntu would be great to
use as well. I'll do some research and see if there is a good reason
we should pick one over the other.

Maybe this is something we can add later, and focus on bridge/relay
support first?

Yeah, I agree.

I'm sure it would be useful for a number of users. I wouldn't be too
difficult to include, and maybe the web interface can have an on/off
button so that they can choose whether or not to enable the Tor wifi
network.
