Well they have an SRD (or PRD) so as long as it would follow the same as LEW's OGL only policy then that should work.

Not sure if Golarion is OGL... pretty sure it's not.
I'm sure more than a handful it looks like PF is going to take over as the game system of choice here in Playing the Game by the end of the year, and I'll be stuck out here all alone with my 3.5 Core books and no group.![]()
