I doubt it.
Microsoft wouldn't share any of its toys with Sony, unless it had to.
There is a server for the pawn system, but i'm sure its console exclusive.
For instance in the xbox version I can search by Xbox Gamertag, but not psn ect
Well shoot. I was really hoping it would be possible. I've always wanted to play a game where I can share things with my friends over the internet. The Xbox just doesn't seem to be the right one, though. I can't afford the gold membership with all this new stuff for the consoles my roommates keep buying.
Mmm, im in a tight money spot too.
But it said 2months for £2 on the dashboard and that was a dream come true for me

Look for special offers on the dashboard
