Do you have actual experience with users establishing Adobe Flash RTMFP P2P connections in the real world?
I've heard a couple of people say only 50% succeed, but that sounds suspiciously low and the people saying that are probably all repeating the same rumor. My own very limited tests with various friends & colleagues work 100% of the time, as long as they have Flash Player 10, but that's obviously not right either.
Do you have some data from a largish test or deployment of home/corporate users?
