We have a number of people interested in buying machines. Typically they can
afford the basic unit, but the cost of a disk pushes them over the edge. Anyone
know about third party disks? Ones that can fit inside would be nice, any
thoughts would be helpful.

Also, is there some way to eliminate all the duplication in the server disk for 
all the diskless clients? It would be ideal to be able to stick all the custom
stuff, and /usr/users files on the swap disks. Can this be done? Is it a good
idea?

It's not hard to do this, though it's not a "supported" configuration.
Generate a kernel with the disk device driver and boot it.  Make a root
filesystem on the local disk (newfs /dev/rrz?a rz??) and dump the current
root to it.  Generate a new kernel that expects its root on the disk, and
install that as vmunix in your new root filesystem.  Reboot and enjoy.

I'd advise leaving /usr/users on a central machine; it's much easier to
administer and back up that way.
