I do precisely this at my workplace.

No.  One can have them set up as separate users, with .forward piping
to procmail or directly to bogofilter.

One per user is more accurate if you have conscientious users.  I have
a few, but most of my users don't bother bouncing messages to the
.NotSpam and .IsSpam boxes.  So I run a single dictionary and let the
preferences of the conscientious ones prevail ;)
