People are already doing it. You just have to be on the same side and log in on the same moment and then check the connections log that you get into the same game. Sort of beats the purpose of the random match style that Pantheon is supposed to be about, but cheaters do anything they can to get an edge and climb rankings, sadly. Check out the Pantheon leaders (the KOREA-people), foran example of this.
The funny thing is that they then complain on the forums that they can't find worthy opponents...
