You probably can do it, but my gut reaction is: don't. RAM for the
workstation should be fairly cheap, and I wonder if the increased network
traffic, server hard drive thrashing and slow workstation swapping would
be worth it.
Also, absent very careful inspection of the network code, the virtual
memory manager and other parts of the kernel, I fear you could get into a
race condition between the network code and the code that causes a page
fault. Or does nbd take care of this for you? I'd approach this very
carefully and with great skepticism.
