Vista Key Generator a Hoax?

That report of a keygen script that can generate a working key for Microsoft Vista has turned out to be a hoax, sort of.  ZDNet reports that the original source of the script says it was meant as a joke, and urges people to stop using it.  At the same time, the script does seem to generate keys.  Whether these generated keys will actually activate a copy of Windows Vista is unknown.  It sounds unlikely, but not necessarily impossible.  Read the story here and draw your own conclusions.
