BigBlueButton: Open Source Web Conferencing

Massimo Di Pierro shared an interesting resource with me: BigBlueButton

BigBlueButton is an open source solution that supports sharing of slides (PDF and PPT), video, chat, voice (using Asterisk), and desktops. The support site for BigBlueButton is a little sparse at the moment, but this looks to be an extremely useful (and cheap) way of running a webinar or videoconference.

Well worth checking out.
