Anon has it right: it is too large of a project to attempt (absent a
substantial community willing to work on it, and that would require having
real problems that need to be solved). Just running my all-Ada mail and web
servers would require a file system, TCP/IP (sockets) implementation,
bootstrap loader, keyboard and screen drivers, and task manager. (The latter
could be "borrowed" from the Janus/Ada runtime, but the others would need to
be built more-or-less from scratch.)

I once (when I was still in college, so this was a long time ago) created a
mini-OS in Ada (built on top of CP/M device drivers), but I never got much
further than the file system. And I probably had a lot more time and energy
then than I do now....
