Funny, I am doing something _very_ similar.

¡Ouch! Threads are exactly the solution I used, and for two weeks now
I've been trying it with very good results (I read the faq also, but
assumed if I kept all livemedia-related objects in its own thread
without sharing with objects of my own, there would be no problem).
The event loop is run in its own thread, and the main thread creates
the MediaSessions and adds them to the RTSPServer as needed.
There's not really mucho more to it, but if there is an actual danger
in this, I'll review it all.
So, well, I guess I'll be following this thread closely... :)
