I completely see the point. Thanks. Anyway, for now my idea is to have
a baby version of AGO, where non-compiled add-ons
can be maintained and all addons can be showcased. The problem of
distributing binaries, as you point out is much more difficult.
Anyway, I will be using the new version of AMO, which is written in
Django instead of CakePHP, so this should give a little more

Thanks for sharing this model. I can totally imagine a Gnome
