Your headless nodes, are they also diskless? Or, do you have a disk on each
node, from which Linux boots, etc.?
Getting the data in and out isn't as big a problem (at some point it is just
a binary or ascii file, which can be read by whatever means.. I can't
imagine wanting to create native .xls files, for instance), but can the
WinNT box serve as the NFS (or whatever) server, and also handle the boot
requests from the nodes.
