Windows source leaked?

Among others, /. is reporting that Win2k and WinNT source code may have leaked. http://slashdot.org/article.pl?sid=04/02/12/2114228 Does anyone here have any good evidence as concerns the truth or falsity of this claim? Lots has been said about OSS developers not wanting to look at this for fear that they will be "tainted." While it is true that simply the act of looking at the code is unauthorized and illegal, I wonder if there is any truth to the claim that a developer who looked at Windows source would endanger future projects (assuming, of course, that simple copying---which is clearly illegal---doesn't happen).
