This works fine if the computers are connected ONLY to one network (network A). My computer (which is also running said software) will listen on port XXXX for the multicasts.

I have a Silverlight app that needs low-level socket support. It's an Out-of-Browser Trusted app, so it has more network permissions. But, I noticed that that Silverlight only supports limited TCP sockets, even with elevated permissions. The method "SetSocketOption" has been removed too. I didn't think that was too big of deal as I knew ...

As part of this communication framework, I am contemplating using google's protocol buffer (PB) for representation of the transport data instead of re-inventing my own binary structure.
