The answer is yes, you can. We have used this in previous projects and, although I cannot guarantee you 100% that 4 of us worked with the same TM, I am sure that 3 of us did.
It's possible but I think it's an economic nonsense.
E.g., if you use DVX, you have almost five user licenses for one Studio Professional.
I.e. 5 x 660 € against 2999 €, AFAIR
No advocacy (i.e. I don't want to start a DVX/Trados flamewar) but you can find a lot of damn cheaper (and sometimes better) solutions which may do the job you need.
