That particular license is bound to that PSN account. Then you bind that PSN to your SEAM if I remember right. Not sure just how the character data is linked though--if it's exclusive to the PSN or not. You can log into that PSN account from other systems though, so it may be bound to the PSN data somehow. Don't recall any case where they moved data to another PSN account--that may be more of a Sony thing than SE.

This is something you should take up with SE through their support portal--confidential info and what-not you don't want posted on an open forum. They're real picky about manipulating character data directly in the databases though. Technically it can be done... they just don't do it for the most part. Won't know until you contact them about it though.
