No, it's a good question.

The Win4Lin approach installs drivers for "virtual devices", like Xen does
from disk and network. It also pretends to Win9x that it's somehow running
on DOS and emulates the DOS syscalls Windows needs to run. The Win4Lin host
kernel patch adds support for these syscalls.

One could imagine some sort of minimal OS that provides enough
functionality for Win9x to run on by emulating DOS-like functionality.
That'd be kinda cool but the straightforward approach would be to get the
Win4Lin patch to apply to XenLinux - it should be possible to do this with
some work. I think somebody's trying it at the moment - there's a recent
thread on this in the mailing list archives, which you may find relevant.
HTH,
Mark
