Is cross platform multiplayer possible?

As Borderlands 2 has been released on multiple platforms, would it be possible for me to play Borderlands 2 on PC with a friend that is playing on a PlayStation 3 or Xbox 360 or is it only possible to play with people on the same platform?

Solution 1:

The short answer is NO, for now.

According to the Gearbox community manager:

Cross-platform multiplayer is something we'd really like to support, but is also something that historically been pretty tricky to implement across all platforms. It's something we're continuing to look into, both for Borderlands 2 and our works beyond, and hopefully something we'll be able to do in the future.
