I'm testing using an AIR on Android application, and using WiFi all data
comes trough as it should. Switching to 3G no P2P data comes through,
but isRTMFP and isP2P are still both true. I will see if I can block UDP
on my router to check if that gives me different results.But I guess it
does seem like I will be forced to rely on implementing a timeout to
check if a client is unable to communicate using UDP, since isRTMFP and
isP2P cannot be trusted in all scenarios.
