Agreed. It's currently in `how close can we push these
halves of Uranium 235 together with our bare hands without blowing
ourselves up' speed of development. Lots of stuff left to hammer
out on the kernel side.

(Our libraries, on the other hand, and pretty solid and
pretty spiff - please don't let the immaturity of the kernel
code keep you from the library side of our endevour - and yes,
Virginia, it libGGI apps will run on X. And SVGAlib. And AAlib.
And IRIX. And FreeBSD. And....)

Your only weak spot - no VGA framebuffer.....

Ditto with the current GGI-EvStack code. It's all a config
option. We even provide in the EvStack branch a `conlinux' linux
console emulation helper to allows SVGAlib and XFree86 to work,
provided you haven't install a KGI display driver.

However, as Geert said, I'm getting ahead of the game here.
GGI/EvStack `Will Be Ready When She's Ready' - namely, at Linux Expo
we (Andreas, Steffen, and I) will be giving talks on our `foolishness'
- I cordially invide you all to come, have a listen, and provide
comments on our project.

Oh, and by the way, I Like VI. I'll pull a paint gun on
any of you Eight Megs And Constantly Swapping lisp-lovers! ;^)

Agreed. This type of well-architected code should have been in
the kernel from v1.0.

True. Getting 3 cards in the same machine to work with different
video modes without stepping on each other in an ix86 machine, is a
whole 'nuther ball of wax. Which is one of the reasons behind GGI.

If the IBM PC wasn't such a piece of shite, do you really
think we'd have spent three years on this hairball of a problem? ;^)
