LispOS directly on hardware or on Unix kernel?

Those are "Unix" programs? People are users of those
on Macs and PCs.
I want to get rid of stuff like csh, sh, cp, tar, cpio, named,
sendmail, nfsd, ... and all it is built on.

Why would someone want a new OS? Much of the Unix stuff that is
concerned with reading random files in exotic formats and
generating other files in even more exotic formats will go
Replace the "files everywhere" metapher with "objects everywhere".
Genera demonstrates how to **integrate** software based
on access to objects and applying functions on them, rather
then piping text around.

For me the ability to run Windows and Mac programs would be much
more important. Unix is only a small fraction of the market.
Windows NT already happens to conquer parts of the server market.

I have no solution for that. I don't really use Unix on my home machines.
What should *I* do? I would lose Photoshop, MCL,
Eudora, NewsWatcher, Acrobat Distiller, FirstClass,
Claris Organizer, Newton Toolkit, Pointcast, MSIE, ...
Cool commercial Lisp environments like Macintosh Common Lisp 4.1
and Lispworks for Windows 4.0.0 are to beat, too. I have them -
why should *I* use the Lisp OS?

I don't want to be cut off from Mac, Newton, Windows NT either.

Which has not been delivered yet. Why? Because it is extremely
complex to put a current OS on a Microkernel. Ask Apple.
They failed to deliver. Despite a legion of
developers. And despite of hundreds of millions of dollars.

Pretty unrealistic. I can have Mac emulators on PCs, PC emulators
on Macs. Pretty much unusable for *real* work.

On Genera they ran the X-Windows server. It was written in C.
On Genera they had TeX. It was *not* rewritten in Lisp.
Go figure. It was not perfect, not fast, but then - it
was ten years ago.

I don't need Unix-compatibility (the ability to directly
run Unix software) on my Windows NT. Why would I need it
What are the benefits of a Lisp OS when you are not using Lisp
software? That is Lisp applications?
Mail server in Lisp, Mail reader in Lisp, Webbrowser in Lisp,
vt100 emulator in Lisp, Editor in Lisp, ...
If we are talking about superior programming productivity,
better abstractions, more stability, user friendliness,
extensibility, - then we have to deliver. *DELIVER*.
Not write mails and post news - actually write
lines of code - not another Lisp. Write applications
in Lisp. This is where it lacks. Demonstrate the usefulness
of Lisp. Don't use some random mail server - write one in Lisp
and make it available. Get a project from CL-HTTP
and make code public available. Just look at ftp.digitool.com
and see the large amounts of cool Lisp stuff for
Macintosh Common Lisp. Get the source for the cool multimedia
development environment SK8 from Apple: http://sk8.research.apple.com .
Port it. Off you go.
Define a kind of "Hardware Abstraction Layer", port this stuff
(HAL + applications) to other Lisps (Genera, MCL, LispWorks, ACL, ...)
and it won't only run on the new OS.
