connect to xbox server.

hey, guy do you think it will be possible to connect to xbox server with PC version cod?

i heard that xbox and PC game is actually same coding.
and I know PC version connects to a certain server.

lets say we cracked all the code for PC
so if we set to connect xbox server and tweak a little bit of PC version
would it be possible to play on xbox with PC version?


but i guess if it was possible,
probably people would have already played COD4 on xbox server right?


I heard microsoft did a testing of xbox mp and PC mp link each other.
the result was that PC gamer always won so, they decided to not connect each other....

so, it is possible i guess.
any thoughts?
