If I have made the kerTeX distribution, it is also with the (remote) aim
to have a typographical (and drawing too with a modified MetaPost)
system not under GPL and being able to generate an enhanced DVI that
could be transformed with kerTeX own means.
I.e. the goals are:
1) To have a very limited, in size, in code language (C with a limited
dependency on a restricted subset of POSIX.2 like utilities for
scripting), in license (BSD like or MIT---Prote), in dependencies (none
but a libc and the limited POSIX.2 utilities subset),
typographical/drawing system able to render both system documentation
(including manual) and user's writing (including LaTeX);
2) That the system be self-contained: providing everything, including
fonts and till the production of a rendering;
3) The the system be like a "hosted" typographical system, meaning that
every extension ("package") be handled by this system, whatever the OS
it is installed upon---no billions of packages versions for every OS,
but only one package for kerTeX, installing the same way on any OS.
A lot as already being done, the latest piece added being a "patch"
(change file) to TeX so that the latest LaTeX can be dumped with TeX
(LaTeX now requires both the e-TeX extensions and supplementary
primitives not present in TeX). This is in the same spirit as e-TeX and
is called Prote.
The lacking piece is the end: converting DVI to something else than PS
and extending DVI to include drawing primitives so that there is a
"MetaPost" generating DVI (Metadraw). The other points are already
addressed.
FWIW,
