while on one of shell accounts (one with restrictions) i'm not allowed to view the processes (ie, "ps") but i do read access to the whole drive (or what i think is the whole drive). now, this wouldn't be abig deal if i wasn't allowed out of my own directory.
like i said before, it's no show stopper- but hey, this can be easily faulted by restricting read access to the /proc dir.
i got the idea while running a Tiny BSD Kernel (not all regular binaries work under some really small distros) - there is a nifty lil app (in c) for BSD that will read (if you have the rights) /proc and print out a nice list
