Contemplating giving a go at installing GMS on a W2k3 VM to showcase another GW feature that is available to us with our license.

We will be moving to GW8 soon as well but I wonder if the effort of installing GMS would be lost if it does work with GW8(which I doubt)

Also wonder if its even worth playing with GMS if the new Active Sync minded version of a product will be available soon.

What's the scuttlebut/rumour mill on getting from GMS to whatever/whenever the new product will be? Some heavy lifting or hopefully an rather easy upgrade path?
