AS3 with FMS

Hello people, My first post here. I couldnt find a forum for FMSM so, i hope i have posted this question in the correct place. I am new to the Flash Media Server gig. I have just installed Adobe Media I have been reading some docs and watching some tutorials. My question is about sending and receiving messages to a specific peer using rtmfp. Im aware to send messages directly to another peer, you needs to know all the peerIDs. But how you get access to the peersIDs?

Secondly, can you please look at these code below. Has you can see i am in the process of sending a message. I have added time to make the message unique. But when i attempt to send it i receive an error:ponder: Can someone plz point out the error?Finally, I was considering using the NetGroup method to send a data message. Does that have any advantages over this method?

function send():void{ var object:Object = new Object(); object.message = “”; object.time = new Date(). time; object.netConnection.nearID;I hope you didnt get bored reading this long post.
Thanks Harry
