A demo of the Realm Works product from Lone Wolf.  They demonstrate the features using an example from the Emerald Spire for Pathfinder, a future release.  What I like about this is the fact that you can do a fog of war type of game for your party.  More importantly is the fact that you double check your work before revealing it to the party.

This will be ideal for some many gae groups it’s not funny. Where I think it will see a lot of use is in remote games.
