The point of Free/Open Source software is the user's right to use the program as they wish, and (unfortunately?) that includes running it on whatever OS they please. In practise, unless your software is inherently portable to Windows (eg Java etc) unless you actually do a port normal users aren't going to end up using it anyway. A copyright license doesn't really apply to this sort of situation anyway, you'd have to create a heavy-handed MS-style evil EULA that tells people what they are allowed to do with software. Noble intentions, but isn't that the kind of thing we're trying to /prevent/? -DR-
