In addition to chat (IRC) there are som other applications we would need. Like IM, Collaboartive editing, VOIP and so forth,
seems interesting in this regard. Here
is a little discussion about XMPP and Ubuntu collaboration.
I have suggested that obby
should be used for online meetings. As I understand it obby and similar projects
and other collaboration focused projects
are moving to xmpp
And if XMPP kan replace Skype, which seems to be rather popular among the Swedish pirates atleast, it's a huge win.
This seems to be sowmthing to investigate further.
