There is little, or no limit at all here. The only thing you need to ensure
is that you DO NOT ALLOW multiple users into a single instance of the front
end (and, by the way, that front end is a mde..right????).
Assuming you got the correct setup..then the only limits here is going to be
the horsepower of the server it self, and how many users it can support. If
your server can support 200 users..then you can easily run 200 ms-access
sessions (ms-access is only loaded once in this case!). However, while
ms-access has what is called re-entrant code...a front end does not, and
problems occur when you don't give each user their own copy of the front end
(and, it should be mde).
So, as long as you DO NOT allow multiple users into your front end, and EACH
USER that logs on GET THEIR OWN COPY of the front end..then your limits are
only that of your server.
If you allow multiple users into the same copy of the front end...you will
have nothing but problems.....
