The new UDP-based RTMFP protocol that just shipped in Flash Player 10 
will automatically use IPv6 for both client-server (to Flash Media 
Server) and direct Flash Player-to-Flash Player communication if there 
is a working IPv6 path between the endpoints and it is at least as fast 
or faster than the IPv4 path latency-wise. (Not that there are many of 
those these days... but as they start to exist, you'll start seeing the 
traffic on them) It is also encrypted and (in some cases) authenticated.
