I hear it's possible... : )
The complain I hear most is that newer games don't even have a local multiplayer mode (we used to complain it didn't have online maybe 10 years ago...)
Besides I'm pretty sure you can fake 'local' using a point-to-point tunnel of sorts — it's just an IP, right? — whereas good luck to workaround online servers.
