i'll post it if you want it..
its a 100% working to get system Link for 2 xbox systems over internet working.. (You'll have to tweak it for more)
99% of the work gets done by "generic" network packet capturing classes that I wrote, and then added a XBOX class that inherits and extends the generic class to capture ONLY XBOX packets..
Then there are also classes for injecting RAW packets into a network.. and then of course the usual listener/server pieces for tunneling over internet ...
let me know and I'll gladly post it online !!
