So what with Wave being the hot new thing, and smart phones being the other hot new thing, the thought occurs to me. With a game of D&D or what have you run on Wave (or, honestly, any PBP platform, but I'm currently enamored with Wave as a PBP platform for reasons of ease of set-up, interface, and flexibility; we'll see what I think once the 7th Sea game is in full swing but early tests look good) and a mobile device with internet access, one could conceivably play anywhere, all the time.
Screw animated miniatures and digital dice rollers. That's the technological revolution I want a piece of. No matter how bad of an idea it will inevitably turn out to be.
