no, they only have ftp access, anyway
But they can practically put any executable, or at least, any PHP code, on the server and invoke it, right?
So what would prevent them from putting some SSH server and executing it, for instance?
thanks for all the suggestions, though, given my current hardware and
software constrainst, not sure if they'll fit
UML always sounded to heavy to my taste but Virtuozoo (which as far as I'm aware is similar in spirit to vserver (linux-vserver.org)) sounds like a pretty efficient way to separate users without requiring hardware virtualization support.
Actually - maybe even Linux under Xen will do the trick on old hardware with acceptable performance penalty.
Might worth a check considering that you don't want to invest in hardware.
Cheers,
