I have seen a couple of references to GMS and BES working on the same

I just wanted to clarify that if we used the MSDE (installed locally to
the server) option for BES, that they would still work together?

Does GMS use MSDE as well? (I would have chosen the default option,
since we do not have any MSSQL installed)

If we have about 20 non Blackberrys (GMS) and 10-15 Blackberrys (BES),
how much RAM would you recommend for the server that would run both GMS
and BES? I was thinking about 2 GB.

Thanks for the advice,
