It depends *heavily* on what processes they are running.

- A bunch of users running Mozilla and Emacs will chew up memory Purty Fast.

- If they are running things with small memory footprints, the number
of users could grow Purty High before things fall down.

I'd expect memory to be the primary constraint.  That's what we used
to chew up when running a dozen users on a MicroVAX with 32MB of
memory...  Eight Megabytes And Constantly Swapping was a pretty big
memory consumer...
