Work has calmed down a bit, so know i have time to get back into this. To make any significant progress i need to find the list of trusted keys the xbox uses to connect to servers. I am going to go ahead and say this is probably in the dashboard binaries, as dashboard binaries were updated with xbox live features added. But that is just speculation, i could be very wrong. So thats where i'm at now, i'm going to do some more research into where this information is located, but the dashboard is quite a bit to disassemble.
