I know Sony are bastards with DRM - it was one of the reasons why the PS3 was delayed from Spring '06 to November 17th. And who can forget the rootkits?

But I'd bet your bottom dollar on it that you can access your PS3 Network account on any PS3, anywhere in the world.

But it does wait to be seen. I've got my account (Lenny1882 as my tag... some bastard took Lenny. ), now I just need the PS3.
