while we're on the get-together topic :)
I've built a small platform for audio seminars and workshops: http://trrtrr.net
The primary goal was to set up discussions on IP telephony technologies (hence the name), but I'm completely open and if someone has a good topic for discussion, I'll gladly pass the moderator credentials.
The conferences are automatically recorded, and then can be easily published somewhere like SoundCloud.
cheers, stan
