Fiio does have the X5 which has a similar jogwheel but I agree with you that the lack of exponential scrolling does make it annoying. Not sure if that's patent-encumbered (fuck UX patents) or what.
Rockbox does have exponential scrolling, but only supports a limited list of hardware. There is an "unstable port" for the Fiio M3k but that's not what either of us own ;)
Might be a good project for someone here who wants to play with embedded hardware! It's one of those situations where once you get it up and going on a particular set of hardware, you will benefit from a lot of "passive" development from others, both past and future.
