OS X on non-Apple Intel iron

Jon notes the challenge to get the Intel version of OS X running on non-Apple, Intel-based hardware has been met.
It will be interesting to see how this affects both Macintosh hardware and software development moving forward. It would seem that, since this is a development build of Tiger, it would be relatively easy to pull this off. I’m sure the shipping version of the first for-Intel Mac OS will have appropriate countermeasures in the code to prevent this from happening.
