rtmfp peers

Hello All, This is my first project using Adobe Flash Media Services. I'm still learning but I find it all very fascinating. I am attempting to build a 1 to 1 video chat application.

I want to distribute peers in a rtmfp group using a single server. I have created a groupspec and giving it sme properties.I understand peers add other peers in has neigbors in a group if they know the name of a grouspec however, I am unsure about the FMS introduction flow process to establish direct communication between random peers.

In the API I want a user to click on a to generate a random user can  somebody show me the code how to do that?

Thanks
