[zlvvamaa] Distributed vs Virtual memory

Compare the speed of virtual memory on a local hard disk versus going over the network to access a remote computer's RAM.  Both are likely pretty bad, but which is worse?

The latter could be accomplished by NFS sharing a ramdisk, which is then used on the other computer to hold a swap file.  Possibly useful for a small cluster.  We would like some way of keeping the operating system on local memory, and only allow an application to use the network remote memory, so that a network or NFS fault will only crash the application and not the whole OS.
