moving user home dir?


i have a box running os x that is publically available to a small group of individauls and i would like to limit the amount of disk space they can consume. i am sure this is a trivial task on most *nix distributions but exactly how on os x is baffling. i figured that i could create a partition and move the public user's home directory there as a hacked solution but i am not quite sure how i would go about doing this. is this a job for netinfo manager?

thank you for any help you can provide.
