Yes (although this is not yet implemented). In particular on windows,
I want to implement a scheme so that you can convert from eggs to .exe
and vice et versa, so people can still install as exe (or msi), even
though the method would default to eggs.

Yes, there are things like 0install or autopackage. I think those are
deemed to fail, as long as it is not supported thoroughly by the
distribution. Instead, my goal here is much simpler: producing
rpm/deb. It does not solve every issue (install by non root, multiple
// versions), but one has to be realistic :)
I think automatically built rpm/deb, easy integration with native
method can solve a lot of issues already.

On windows, this issue may be solved using eggs: enstaller has a
feature where dll put in a special location of an egg are installed in
python such as they are found by the OS loader. One could have
mechanisms based on $ORIGIN + rpath on linux to solve this issue for
local installs on Linux, etc...
But again, one has to be realistic on the goals. With toydist, I want
to remove all the pile of magic, hacks built on top of distutils so
that people can again hack their own solutions, as it should have been
from the start (that's a big plus of python in general). It won't
magically solve every issue out there, but it would hopefully help
people to make their own.
Bundling solutions like SAGE, EPD, etc... are still the most robust
ways to deal with those issues in general, and I do not intended to

Distribution is a hard problem. Instead of pushing a very narrow (and
mostly ill-funded) view of how people should do things like
distutils/setuptools/pip/buildout do, I want people to be able to be
able to build their own solutions. No more "use this magic stick v
188.8.131.52.14svn1234, trust me it work you don't have to understand"
which is too prevalant with those tools, which has always felt deeply
unpythonic to me.
