I'm verry interested in that too. My solution at the moment is running
nbd-server in a virtual machine to make it not local.

But maybe NBD is the wrong thing for this. For a strictly local setup
there i no reason to pipe all data through the tcp/ip stack. Maybe we
should develope a BUSE (Block device in Uer SpaceE) just like fuse and
cuse do for filesystems and character devices already.
