Now you're starting to see what I've seen :-/ I also worry about your
APs and networking infra -- to support 400 active users you'll want at
least 8 APs. In more realistic terms, you'll probably need 12,
assuming a reasonably balanced load.

As I mentioned before... I am working on xs-0.6, with the
moodle-ejabberd magic.

Well, that's 1/4 of your RAM. You need to budget for apache/php,
postgres, and squid. Right now the main problem is Squid.

Thanks for the list below. Quite a few are about stuff I can't help
with (roof leaks, power cords...) the others, I'm working on...

cheers,
