Mark will correct me if I'm wrong, but TNL doesn't support multicast 
protocols out of the box; it's much more focused on connection-oriented 
behavior. It would probably be possible to adapt some of the "internal" 
code (ie, the basic RPC serialization code, the encryption code, etc.) 
to work in a multicast situation but in general you'd end up tossing a 
big chunk of TNL out the window to do it.

It's something I'd suggest not doing unless you have fairly deep 
knowledge about multicast...

Anyway, TNL connections are pretty lightweight - have you considered 
just having an NxN network topology and sending the data out that way? 
Obviously, you'll burn N packets instead of one, but it'd be quick and 
easy to get running...
