I think I am understanding. My claim is that different distros are
sufficiently dissimilar that we would end up needing a different bundle
for every distro. The dependencies, even if they have the same name, do
not provide the same API on different distros.

No. I am proposing to "bless" an existing multiplatform distribution, and
then use this distro as an overlay over the base operating system. Gentoo
Prefix happens to be the only existing distro of which I'm aware that is
designed to be installed without root privileges, but others should also
I am advocating this approach in part because it also solves the "Case 2"
problem, of dealing with new Activities written in (platform-independent)
C. These activities can be bundled as SRPMs, ebuild+tarball, or whatever
the appropriate packaged-source format is for the blessed distribution.
