No. openMosix is a kernel patch of Linux. It cannot be used for windows,
and I'm absolutely positive that the developers will never port anything
like it for windows. Sorry.

In a typical LTSP setting where the users are running Xwindows, that is
about the only thing that *is* running on the client computers. With the
echo 1 > /proc/hpc/admin/lstay line implemented in the How-To, this keeps
all client processes (Xwindows) from migrating. They stay put. Your
client PC runs your Xwindows session. This is a good thing. If your
Xwindows processes were to migrate to another user's PC and they turn their
machine off, your Xwindows session would very likely (almost positively)
hang.

Thanks for your interest! I hope you have success implementing the How-To.
It will not only get you going in clustering but help you learn about the
process of compiling custom kernels (if you haven't been there yet).
Enjoy!
