Okay, so the people I'm living with are being dumb about computer usage, since one of their wintel boxes went down, and they're complaining about how there's a password on my PowerBook (for good reasons). Anyways, I've decided to setup a limited user account for them to use, with limitations.

So what I want to do is set a disk-usage limit for them, of around 1gb. So that once they fill that up, they can't download whatever anymore. The problem is, I don't know how to do this. Is it even possible?
