Maybe.

One one workstation, I have 128MB memory (physical). And I still use
around 140MB of swap. This is used by two users doing X (one local and
one remote) runing web browsers, email clients, numerous rxvt's, etc.

I guess it depends on what they are doing and using.

When I build software like glibc or qt, I can really use up memory quick.
I have several systems that have a full gig of swap (and 768MB to 1 GB of
ram).
