I just would like to announce Network Block Device - thing that allows
one device to lend its block device to other machine. It also allows
you to write block device driver in userland etc. You could for
example use it instead of nfs.

Currently, it works over TCP and it is _not_ possible to swap over it.

Well, when I saw patches to swap over NFS... Hmm, this would be more
reliable than swap over NFS! Well, but it can deadlock, anyway.

(I actually tried swapping over it. On 16M machine it was ok, on 4M
machine it deadlocked. Swap over nfs would deadlock, too :-).

More info, sources look at http://atrey.karlin.mff.cuni.cz/~pavel/nbd.

Good luck.
Pavel
