LispOS directly on hardware or on Unix kernel?

Indeed, we shall *eventually* get rid of it.
But until we are able to, why make without them,
whenever they are expedient?
And even then, a successful OS will need talk with all the legacy protocols,
and free un*x sources can prove a valuable capital to reuse.
In any case, all this is sure no priority,
so until we get the essentials,
let's use whatever is expedient for these details, whether C or LISP.

Not everyone of use has many machines to choose from.
Most LispOS users will have only one machine,
so until the happy times when LispOS can really do everything,
keeping the ability to run On Top Of Posix will be great.

You're preaching the converted.

Yes, and among these, proprietary software and hardware.
Let that never ever happen again.

The LispEnv project in CommonLISP might be ready in one or two years.
The SILK project for a 100% Lispy system might take more time.
And if you want a fully Reflective architecture like Tunes,
I'd be happy if it's there in 5 years.
