This sort of clean-room approach is taken when reverse engineering
commercial products because, or so my understanding goes, if there
happen to be similarities between your implementation and the original
implementation, it's much harder to get nailed for copyright violation
if you can prove you took steps so that the guys who wrote your code
weren't the same guys who looked at the plaintiff's code.
I suspect the same issues surround GPL'd code, except that it's harder
to prove separation was maintained.
