Well, I guess if you're that much of a diehard, just check out this project instead: http://www.duo3d.com/ they're planning on fully opensourcing everything. If you're annoyed because of the apparent dependency on ubuntu, note that I got things working on gentoo without much issue: http://www.keyboardmods.com/2013/03/leap-motion-in-gentoo-li...
Yes it definitely works and does so more easily than any alternative I've tried. I've used it to interface quickly to something like 20 different APIs at this point.
Thanks for your work on rauth, I've been using it for a long time and I'm hoping to update my projects to use the latest version to pick up requests 1.x support some time soon.
A very small corner case here, but on certain keyboard layouts, hjkl is actually harder to use than the arrow keys. To be more specific, I use an alphagrip keyboard most of the time where left,right,up,down are all under the left thumb and a trackball is under the right thumb. The way I interact with vim is thus very different from most folks, I imagine.
