Update-
Basic Summary: 
Besides the regular asset/mechanics grind, we can send and receive packets from Unity to an Eqemu server, but we have to do a handshake for each packet (which is our current networking issue).
Advanced Summary:
We are halfway/half-assed through setting up the EQ packet protocol checksum. 
The packets are the easy part, but the protocol acknowledgement system is still unimplemented (
OP_Ack) which is our current "hangup".
I've included the 
Prototype's Source below if you want to check it out.
