Yup. There are many folks that use VTTs only in face to face gaming just because they want the features that they offer that enhances the gaming experience most notably Fog of War and Vision Blocking. Both of which are extremely difficult to manage on a table top.

I'll be working on a demo of what current VTTs have to offer probably this evening and I'll post it up so that those that may have never seen one in action can get a feel for it.

As for the projector/laptop setup, one serious word of caution. Do not use the white board. For those that aren't real picky, it will work, but for the majority it will irritate the heck out of you. It would be better to project on to a wall than to use that white board. The best idea is to get a screen or a big sheet of matte finish slightly off white paper. The white board will reflect back a bunch of light and your players will have to be moving around just to see what is in the middle of the board.
