Somehow hackers are pirating iPhone apps right now (you can find pirated apps for free to install on jailbroken iphones). I don't know how they are doing it, but if the Mac App Store will work the same way, they've already solved it.
if i'm not mistaken, on the iphone they've just disabled the kernel checks that require binaries to be signed before running.
Disabling the kernel check means after you take the program off one iPhone, modify the binary to disable any DRM check, you can then copy it to another iPhone which is able to run the unsigned binary.

i'm not sure how apple is doing it on osx because it has to run lots of binaries that will never be signed.
