Do your users have Web access? If so, you can set up an Rweb (or
similar) server that could run the jobs for those users. I have one
set up like that. Users transmit their code via http and can get
results back in web page.  I think you could probably program around
the output management question, but I did not try to do it. I mean,
something like "wget" could download the images directly, by-passing
the http server.

Rweb has been abandoned by its original author, but it can be made to
work, and there are other, newer http server programs to run R.  I
have not tried them yet, mainly because my customers needed to run
Rweb because their clients told them to use it.
