Naturally. The cpan-all repro would be focussed on distributions not
authors, so I figured a structure (for Foo-Bar and Foo-Bar-Baz distros)
something like:
/Foo
/Bar
/Foo-Bar.distro/...
/Baz
/Foo-Bar-Baz.distro/...
(Let's not bikeshed that at the moment - the key point is that a
hierarchy is needed and that it be focussed on distros.)

I doubt it, but we won't know unless someone tries it :)

Great.
