I've manually done it before (on Linux). Technologically it's not that hard to do, but legally is where it becomes a problem. IIRC the Xcode license (which applies to the iOS SDKs) requires you to use them on Apple branded computers.

I don't know why Apple cares so much about that, especially since they're already collecting their yearly $100 tax from developers on top of the 30% revenue cut. I guess at their size, extracting every last penny is how you get to a trillion dollar valuation?

So unless you have a strong legal defense ready, you should probably just pay Apple.

EDIT: I should clarify that by "it's not that hard to do", I mean that it's easy because someone else already did the hard part :)
