looks intriguing. I have to wonder (being a Jabber guy) if he's
using some HTTP/XMLRPC mix to back this stuff or if he's using a

how he intends to get people behind firewalls involved.

scale. But it doesn't matter, this clearly is the bootstrap
phase. Perhaps the right answer is to retrofit something like
Jabber underneath all of this.
