I think that's a little different. Fedora allowed an unprivileged user to 
install a package, but giving the package full privileges.

For 0sugar, I assume, the user is fully privileged (it's their machine); 
it's the package that should be restricted, not the user.

This distinction has caused a lot of confusion in the past, and I've now 
added a section to http://0install.net/injector-security.html to try and 
clarify it.

I've also added a demonstration of using 0install for sandboxing, showing 
how sandboxed processes can still share libraries (which doesn't happen 
if you just create lots of separate RPM databases):

Hope that helps,
