Cycling computers could probably do this for you. They have your speed & your cadence, and if you entered in your cassette & chainrings they could show you your current gear & the next gear up & down (and how to get to it).

I'm not sure how useful it is though. It's not often I'm prepared to do a back & front gearchange at once - I just loose too much speed when I have to easy off the gears.

I suspect that as electronic gear shifting (Dura Ace DI etc) becomes more prevalent the gear system will take care of this for us, though. One click = next gear, no matter how many physical shifts it needs to do.
