Ah well Norm Hardy (KeyKOS) is on team Mill; the Mill is very much a bunch of caps vets :)
The Mill isn't a Capability-based Addressing machine, but it is very much a machine that hopes to push normal programs and operating systems in the Capability Object Model direction with first-class support.
Now you are using a bugmenot login so I have no idea who you are, but if you're a caps vet we'd love to know your thoughts :)
