When you play more than one online in Little Big Planet you can either login as a guest or to another PSN account. So that should not be a problem at all.
And if it where, just let the 2nd player play as "Guest" or the same nick as player 1 but with a number added to it.

Then how can you play more than one online in other games? =P
