@DJ, have you thought about making either decals or stickers (small, medium, large) to pack with the kit? Maybe it could say, "Powered by EZ-B" and/or www.ez-robot.com"?
I think that most people wouldnt mind putting at least a small tag on thier bot for you. Then every video and picture could possibly get you even more exposure.
I know I would do it for ya.
