By having distinct packages built separately for each distribution by
experts. This is incompatible with our (or at least my) goal of allowing
users to throw packages around as atomic objects, without internet access
and without having to understand anything beyond "my friend has Sugar, so
it will work". It is also incompatible with allowing novices to generate
This is also incompatible with your proposal to "choose RPM". The
equivalent here would be to choose RPM on Fedora, DEB on Ubuntu, ebuild on
Gentoo, tarball on Slackware, etc.

Because there is no way to build a single binary that will safely link

We can't pick one, because we wish to run on them all. We can't pick
many, because then users cannot share Activity bundles.
