True - but that also means that you can have multiple implementations behind WPILib. We're actually doing that in the main source code for WPILib, with the actual code and the simulation code. It's cut into three projects - common, simulation, and real, and both the real and simulation project implement some of the classes separately.

I suspect that the initial implementation of HAL involved cut/paste all the ChipObject stuff from the existing WPILib implementation into the HAL code.

Fair enough.

Well, I don't think they want the WPILib source code public yet - which is the issue, unless you plan to keep you work private for a while.

I'd also consider helping, but I also have a large backlog of pending work.
