Thanks for the info Dele -always nice to see an actively maintained community around a project.
For the time being we're on Flash+XMPP for browser compatility reasons. The way things are currently running is that each client starts a new (seperate) conference to an outbound SIP call - We're looking into how to put multiple XMPP+Flash clients into the same SIP conference (if they're requesting the same media) - This should help with the load. Any pointers or suggestions for this method? I was reading some CANDY documentation and it said it was do-able, I'm wondering if this translates to Red5.
