That is kind of what I was thinking of myself. :-)

All we need for the frame work is
a module to receive (TCP/UDP/Whatever) and convert to internal Framework
format
AND
a module to send (TCP/UDP/Whatever) converting from internal Framework
format
We can do some testing to see what works best!
Yes you're right over a LAN UDP is almost as reliable as TCP

YEP! My view exactly!
One that doesn't have to be rewritten for every new concept!
