I want to create a channel to which various users could stream their desktop. I'm looking for the best solution for them. So far I've found Dyyno (free but too simple), WireCast (expensive and too complex), Flash Media Live Encoder (free).
I need one that is free, simple to use yet powerful enough (notably to stream specific area of the screen, audio from the softwares or from the microphone or both and to run on both Windows and Mac OS X).
Any suggestion ?
P.S. livestream.com and ustream.tv have their proprietary solutions (incompatible with others)
EDIT: hello ? anyone ?
