If I understood you currently then:
Have a server with say /mountpoint and mount multiple client's
/freediskspace to it /mountpoint/cli1, /mountpoint/cli2, /mountpoint/cli3..
and have all the clients mount server's /mountpoint to say ~/User?

In this case, I would say that the amount of userspace available to a user
is limited. It acts more of a "samba like shared-folders" where you have
read-write permission. So, if a person uses up all the space available on
/mountpoint/cli1/mydir he'd have to manually move/create another directory
in /mountpoint/cli2/mydir. Which is not ideal.

Ilug-c members have suggested GlusterFS and openafs, I'd be looking into it
for now, if I receive no other suggestions. (Thanks guys!)
