Software integration X platform

[Zyraz]

I was just wondering , with every part gaming integrated across platforms ... PS , Xbox , PC .
Battlenet
Armoury
Leaderboards on FPS

How long before we get crossplatform games multiplayer?
eg. PC players vs Xbox vs PS 3 Players all on same hosted game .

How hard would it be to do that from a coding point of view ?
Imposible ? Why ?

Don't think it would be hard as it's only the comms & data processing that would need to match on all platforms.

The competitive advantages are different across platforms. FPS would favour the PC heavily. It would be a similar case in favour of consoles when it comes to driving and action (third person) games.

So you're probably thinking what about integrating PS3 players with Xbox360 players. I think it's fairly obvious - MS and Sony each have reason to keep players bound to their own networks (Live and PSN).
