A few weeks ago I put together an experimental UDP connectivity checker 
that relies on Flash Player 10 and its RTMFP stack... the direct 
player-to-player connectivity works without requiring the player to 
first go through a STUN- or ICE-like gathering of connectivity and 
address information, but there's enough hooks in the protocol that once 
a session is up a specialized server can ping the player from the 
outside and then tell it what kind of connectivity it has...

Offered totally without any guarantees or promise that it will stick 
around, on one of my personal servers at:
