Is there a way to access the remote IP of a RTMFP p2p stream?

Question

I'm writing a communication system, using Actionscript 3 and C#. Flash is used to communicate with RTMP server and stream video and audio using RTMFP p2p, but the actual client logic is handled in C#.

What I want to be able to do, is allow users to share files between each other also using a direct p2p connection.

I have got the RTMFP connection working but I need to access the IP address of the remote user so I can initiate a connection to send or receive files.

I looked at the Adobe docs but I can't see anything except how to access the farID.

Is there a way to get the IP of a RTMFP stream?
