Andrew ("Q"), Ash, and Elliot have continued brainstorming.
Posted up a link on the blog [1] to discuss ways to go. Great suggestion (though it might have been a (brilliant) joke?) to make a DDR pad.
Elliot's been messing around with the Parallax RFID board, and learning what it can/can't do, but he's terribly terribly new to RF stuff.
