If you own FF14 on PC and PS3, can you have them both registered to one account? If so, would that be a single fee? It would seem silly to pay two monthly fees for one account, even if it's on two platforms, but I have to ask out of pure curiosity.

To re-emphasise before someone misreads me and says "Of course you would pay two fees for two accounts" -- I am asking if you pay two fees for one account on both PS3 and PC. I know you have to buy the game for both platforms, just curious about the monthly sub. Thanks for any guidance on this.
