Have you seen the new Shimanos that change via servo motors on the derailleurs? Means you can change quicker and you don't get cable stretch, cos the cables are electric rather than mechanical. Sadly it takes a battery rather than being dynamo recharging or anything, which to me would have been the obvious solution.

Not sure whether they're actually out or just prototypes, look pretty cool if slightly unnecessary though.
