I strongly second the stick-to-the-wall whiteboards recommendation!
I actually suspect that the performance improvement for marker over pens is due in part to increased legibility—both from the tendency to write larger when using a marker (I know that I tend to draw really tiny diagrams with pens) and because markers leave a much thicker mark on the paper.
