The patch available from http://qemu-forum.ipi.fi/viewtopic.php?t=2718 adds a new utility, qemu-nbds, that implements a NBD server
I have been using nbd volumes mounted from inside qemu for filestore and for swap, both read-write, served from files and from partitions, with the unmodified standard nbd-server (debian testing version) for intensive work and it has been faster and more reliable than NFS (not that that's saying much). The only thing that doesn't work is the -swap option, which just hangs, but that proves not to be necessary when swapping onto nbd host volume from qemu-land, even when stress-testing it. What problem is solved by a specially modified nbd server?
