Cool idea. That might get me to finally get my lisp feet wet (so far all
I do is wrangle my .emacs file into something that sort of does what I
want even if I don't understand it.)
I hesitate to ask how you will accomplish the speed. (probably way over
my head!)

Hmm, very useful idea. not sure if it applies to anything in my project
but I'll keep it in mind.

Celeron 333, 66 mhz bus (gotta switch to PC100 RAM), kernel 2.0.36. I'm
about due for a major linux upgrade but I like to wait till there's a
compelling reason to get a new CD so I don't have to download quite so
much.

Well, I can just keep my old kernel handy and give it a different LILO
image.
