Share one computer to multi-users simultaneously...Pro & Con?

[ABAMOTO]

Dear all:
I am trying to find a solution to make our warehouse process more efficiently. I figure that I need extra shipping servers (one more for UPS and one for FedEx). One way is to simply purchase two additional desktops and hook them up. Alternative choice would be get a software to host one computer for multi-users at same time.

I would like to know, if any of you ever have done this, is it worth doing? Any pro and con? Any recommanded software? I searched and found www.thinsoftinc.com has some cool stuff (although they charge you $99 per user license).

Thanks a bunch =)

Purely from a backup point of view, 2 separate units would be better. If UPS breaks down, you could ship your stuff using the FedEx PC (AND service) and vice versa.
Both on the same PC is asking for trouble if it should break down!
