Back when Mavic made their Mektronic electronic shifting system, and their earlier Zap system, I remember thinking how cool it would be to have shift buttons on both the barends of an aerobar and reachable from the brake levers at the same time. Shouldn't be too hard to make.
Lo an behold! Shimano has been making prototypes of an electronic shifting system for years, Campagnolo too, and it made me so happy when I saw that Shimano made a time-trial specific prototype of the electronic system. Sweet new TT/Triathlon frames from Look too in that link.
I hope it'll be on the market by 2010, together with 11-speed casettes.
