I presume you mean the NetGroup that comes with Flash Player 10.1 for peer assisted networking.
In that case, yes we do support NetGroup and have multicast A/V Streams and p2p data streaming.
You need to use player 10.1 LCCS swc. Unfortunately, we don't provide the source code for 10.1 but just the swc and docs. Definitely try out and if you face issues, let us know. There are examples like MulticastTest( for multicast A/V streaming using NetGroup class) and P2PDataMessagingTest( for p2p data sharing using NetGroup) that we provide along with your sdk in the sampleApps folder.
That should act as a good pointer to get you started.
Hope this helps
Thanks
