Not that this has anything to do with the question you asked, but do you think there's really a market for it? I haven't tried it, but my bikes shift so well now that I can't imagine spending even a few dollars to make them do it better, certainly not anywhere near $1000.
Of course I go back to the downtube/friction days, so my perspective may be skewed. But, seriously, if somebody offered me the full setup for, say, $100, I don't think I'd take it. I know it wouldn't make me faster, and I don't think it would make riding more fun.
