That's pretty cool, really. If I had to guess I'd say most of the places that have a significant enough installed base of similar machines to use system images probably already have something in-house that can run Windows Deployment Services or Remote Install Services, but "most" isn't the same thing as "all" and there are plenty of places that use *nix for real server work.
I'd be most curious to know if it supports multiboot configurations. Microsoft's tools don't and dealing with that is the biggest imaging related pain in the ass that I put up with.
