I'm curious to see it. Are these electronic shifters supposed to be self adjusting, or are they going to use indexed stops that still require tuning? Still a derailleur, right? Just a small motor instead of a cable?
Has anybody tried the new Shimano gear hub with the electronic shifting? Not quite the same as what you're talking about, but in the end, the rear hub responds to wireless shifting commands from a box mounted elsewhere on the frame.
Rohloff was rumored to be looking into something similar for their Speedhubs, using pushbuttons on the handlebar. Not sure where they're at with that currently.
