I thought it broke down like this: WS2801 - Discrete 14 pin chip, two wire signaling (data plus clock) WS2811 - Discrete 8 pin chip, single wire signaling (data only) WS2812 - SMD 5050 RGB LED with built in WS2811, single wire signaling In any case, I'd love to take a look at whatever you've got. I've got a system that's at least letting me talk to them now, but who knows what kind of tips I might pick up from more examples!
