Just from a brief inspection, I'd observe that the API specification is basically a language independent thing which might indicate that there is room for an Ada implementation. Also, it is at a low enough level that it might not take forever to implement, yet could still be useful. It would also show off Ada's strengths in the way of getting down to the bare silicon - plenty of opportunities for representation clauses and the like. There would probably be a need to build more than just an Ada version of L4 in order to have something hobbyists could play with, but if it could be brought up and running on a garden variety PC, it would constitute A Good Start. It looks like an appropriate level of ambition for an AdaOS project and the hard work of doing requirements, etc is already handled.
