You can't upload the same *tarball*, but that's not what I suggested.

I agree.  Now all we need is a DeLorean, a flux capacitor and 1.21 gigawatt=

I outline the concept of a well-formed distribution here:
http://www.dagolden.com/index.php/308/packages-modules-and-distributions/

I would go further and say that I recommend that whenever possible,
all modules in a distribution should have the same version number, to
avoid the sort of distro/module version sync problems that people have
experienced.
