Re: [Building Sakai] Video + desktop streaming in Sakai

by Adrian Fish Feb 02, 2010; 08:42am

I'm currently playing with BigBlueButton which seemspromising. ...I was actually thinking of investigating Red5for an update of Agora but it seems crazy when

BigBlueButton is around and open source.

Cheers,

Adrian Fish
