Diablo 3, one purchase for Mac *and* Windows, or one for each

diablo-3

Today, Diablo 3 went open beta for the weekend, which means I'm finally able to test it on my iMac. I know Blizzard put a lot of work into both platforms so I don't expect them to behave all that different in terms of performance, but I still want to test both.

But a question popped up, and I can't seem to find an answer to this anywhere, perhaps it is implied.

The pre-purchase, or the actual purchase when that comes around, will that be "access to the game" or "access to the game on Windows", and then a separate purchase for Mac?

Basically, when I purchase the game, do I have to pick my platform or do I just purchase access and can switch back and forth at my own whim?

Does anyone know?

If you log in to the Battle.Net site and choose to Download Games, you can download either Windows or Mac client from there. So it would be purchase once and you can use it on either platform.
