I know I'm late to the discussion, but for the record, I fully agree
with this approach as the probably best compromise between usability
(don't underestimate that, see the emergence of the various "app shops"
for Linux applications), security, and flexibility. If anybody wants to
work on that, I'm happy to support it in the University Linz context
(i.e. as student work, thesis, etc.) and contribute to the process
(although, depressingly but realistically, not the implementation).
