I think you are right. Last time I looked UML didn't support modules and now it does. This looks like a really lightweight solution for 90% of my filesystem development. I'm starting to get a little bored with the crash and burn, repeat as necessary approach :-)

Yes, that matters to me. I would have mentioned Plex86 except it's not quite there yet, though it's looking really good. I'm really blown away by what that group is doing - it's like the inside of a transmeta chip. They have to work around a lot of extreme braindeadness in the x86 design and they do it by analyzing and rewriting code on the fly, then they have to make it look like they never did that, in case the code is checksumming itself, and so on, yikes.
I think VMWare is really a good product, and it's there now. They make it really easy for Windows users to get free. I support them. If they are smart they will open up eventually, and if they are not smart, well, that's what natural selection is for.
