LispOS directly on hardware or on Unix kernel?

Sure, I can buy that. I think from time to time as the system is
being evolved, major chunks of the system wiil have to be ripped out
and replaced. If we can do a half way decent job of defining
interfaces, then hopefully that pain can be localized. The alternative
is to design the whole thing out first, then start implementing it
without changing any of the interfaces. I don't think that's a viable
approach for such a fuzzy project being manned by transient
volunteers. That approach would also mean it would be a long, long
time before we saw the results of (car '(a b)). I'd rather live with
having to periodicly revisit portions of the system than wait for the
"ideal" system to be designed and built.
