I have a camera mounted on my fixed gear, since I only have a front brake the right side brake lever was available for camera control. Pull the lever half way and it focuses, pull it all the way and it takes the picture. The camera is a Panasonic Lumix G3, so it only took 3 resistors and two micro switches, but my point is that it looks like a brake lever and works like a cable release. Making a down tube shifter that works with Di2 would mean making a shifter that has a spring return from a set position, with a switch in either direction. With SPDT information, the rest of the shifter can be put elsewhere...
Wow, I was thinking *way* too small. I think I see your vision.

Kind of "paddle shifters" for downtube Di2? Traditional levers with "return-to-center" springs and momentary-off-momentary circuitry to enact shifts?

Push right lever = shift rear mech down stack
Pull right lever = shift rear mech up stack
Push left lever = shift to little ring
Pull left lever = shift to big ring

I'd buy this!
