Processing incoming audio for broadcasting

Question

I'm sure this questions has been asked a couple of times so far, but I just don't have the time to sift through all the posting pages to find my exact question (though I did make it to page 25).
The purpose:
I'm currently designing a server that's meant to rebroadcast an audio stream using RTP from one connected user to a group of other connected users (remote user speaks, server "captures" streaming audio, rebroadcasts to remaining remote users - all unicast).
The problem:
So far I have tried (server-side):
1) creating a RealizedProcessor using ProcessorModel(MediaLocator*, Formats**, ContentDescriptor***)
2) creating a (non-realized) Processor using MediaLocator(see MediaLocator* info), realizing it, then starting it.
Results:
1) The program hangs up on the Manager.createRealizedProcessor(processorModel) line and gives no errors or warnings whatsoever - just sits there (in debug as well).
2) This seems to work until the next part of the function (where the output from the processor is passed to the dataSinks of each receiving user). I get a "cannot get data output from unrealized processor" error.
If anyone has any ideas on what I should do to solve this problem, please fill me in. :) Thx in advance.
*: new MediaLocator("rtp:/" + addressOfIncomingStream + ":xxxx/audio");
**: new Format[]{new AudioFormat(AudioFormat.DVI_RTP)};
***: new ContentDescriptor(ContentDescriptor.RAW_RTP);

Thx a bunch for the suggestion, lappy. We, after reading your suggestion, are gonna be changing the server to forward the RTP packets to the individual clients - we figure this will lighten the server load and it seems much simpler (...).
I had a look at the RTPManager class and tried a few suggestions they have for the Multiple-Unicast sessions. I tried a few of the things they suggested but I was unsuccessful in implementing it.
So far on the server side:
RTPManager rtpManager = RTPManager.newInstance();
SessionAddress localAddress = new SessionAddress(); // any incoming RTP stream on any port (?)
rtpManager.initialize(localAddress);
// setup forwarding address
InetAddress ip = InetAddress.getByName("142.155.128.34");
SessionAddress destination1 = new SessionAddress(ip, 4446);
rtpManager.addTarget(destination1);
Once the program starts.. it seems that the packets don't make it to the new address. I'm obviously missing something here, or my logic isn't correct.. if someone could please fill me in on some details it would be very much appreciated. Thx in advance.
