There are some efficiencies to be gained by not having a remote disk,
and instead having a remote filesystem.  From everything I have
heard that does not sound like it has been implemented for windows
with NT kernels.

nbd is 600 likes of obviously correct code, which can put full disk
speed onto the wire.  Nor have I seen any issues with it.  That
makes tough competition for iSCSI in modest deployment locations.

I still need to read the spec to see how sane iSCSI looks on the wire.

Cool.  If iSCSI looks sane I will suggest to the etherboot guys that
we implementing booting over it :)
