ATVFlash Licensing

I have two AppleTV Units, one for the main TV room, and one for the basement HT. I want to get the ATVFlash update for them, can I just buy it once and apply it to both units, or is there a funky licensing thing in place to prevent me from installing it on both with one purchase?


A single copy of aTV Flash can be installed on multiple devices provided they are owned by the same individual.
