Stupid GA Beta Question--
 

(For what it's worth, I expect the answer to be 'No, you can't do that.')

Okay, if I pay the $15 and download a copy of Goldfish Aquarium for PC and run it in Virtual PC on my Mac and *then* two months/years later an OS X version is released, is there *any* chance that I could use my PC registration for my Mac version, or will I have to splash out another $15 for the Mac version?

The $14.95 is for the beta version. I bet you another $14.95 that it'll cost more by then. :D
