I am a player on it. I have the lite version. It has been extremely fun, for our group. While there may not be zoom features with the maps it seems that there are various sizes of mapping paper that can be used.
But I think the idea is to re-create face to face table gaming as closely as possible. And in Pen and Paper D&D you are restricted to whatever size graph paper is available and won't have a zoom feature.
The DM of our game has scanned in pictures from some of the monster manuals and can drop those right onto the map in rooms where we find them. It has been really nice, and with my time constraints it is pretty much the only I am able to play D&D regularly now.
We have been using the in game chat feature, but I understand that you could also use teamspeak over the computer and have voice chat, or use a combination of the two.
Another group which has yet to start might be trying the teamspeak voice chat while playing, beofre too long.
I am a huge fan of Fantasy Grounds, but it may not have all the features that you want in a program. Ask me any specific questions and I will try my best to answer them.
