Help on this is more than welcome. It's also not as far off the roadmap as you might think. I know of at least three very talented font designers with disabilities, at least one who uses a wheelchair. It would please me enormously to make a tool suitable for them, and I would push other priorities back for it, just because I consider it so important. In any case, I haven't done detailed design work on accessibility, but enough poking around to get some sense of what might be involved. You are right that stable com-rs will help a lot with this kind of integration; there are soundness and other issues with the custom com implementations we've had to do. Fortunately there are good people working on it.
