I would like to use the following scheme to track -current on my home net:

    1. stable central machine (beefy UW disks, 100bT) SUPs the various
	source collections and NFS exports them.

    2. 8-port switch provides full 10bT bandwidth (modulo some tuning)
	for 7 client machines to the central machine's 100bT.

    3. The client machines all NFS-mount the source read-only, and union
	mount local storage on top of it.

    4. The client machines build -current inside their union mounts,
	without using BSDOBJDIR.

Barring bugs in UNIONFS, it seems to me that this method should work.
Of course I have to be careful about local files obscuring changes
brought in by SUP, but that's a manageable nuisance.

Am I doomed before I start? I think this would be a lot cleaner than
hordes of little symlinks running around.
