My school has whiteboard paint on some of the hallway walls and my dad just painted a wall in his new office with it. A few things: 1) Markers leave more residue with dry-erase walls vs. a normal dry errase board. I suspect that this has to do with the less-smooth texture of the wall 2) It's expensive, like prohibitively so. Expect to spend thousands to paint a single room.
