Well, I'll be back on top of this once I get back from my trip to FOTB. I got to see Xerofall's set up close and didn't notice anything awry. However, it seems that the prototypes with the parallel LEDs/resistors are the better route to go, despite the minor bit of aggravation in putting it all together.
Anyway, as I told some people at FOTB, my intent is to get sponsorship here and have these available soon.
