So you can send me a message.
I also found Open Source Flash – red5 an open source server that cam receive video/audio/data from a flash client and either save or rebroadcast that content. It is in beta but looks like a much cheaper alternative to Flash Media Server, and if is easy I might even manage to install it at home as red5 looks like it might run on a mac. This would provide a way to record on a web page and make something like BubbleShare but would be passed by authority web blocking. I can think of a few wonderful ideas for collaboration between schools if we could customise this sort of stuff.
Anyway it looks like some interesting things could be done here, given a bit of time and knowledge.
