Tie a PSO2 Account to more than one PSN?

[Ryo]

Is it possible to do so? Has anybody tried? I'm stuck in Cali for a week and want to play on my vita, but don't have my hard copy in hand. Can anybody confirm/deny this as a possibility? i.e. When I get home I'd like to play PSO2 on my US PSN account, but I'd like to DL and play on my JP account in the meantime.

I would like to know that as well

I also won't get mine until next week so I'm curious about this too. I thought about buying a second vita so I can play the Japan one while I wait.
