1.a) If the work of the import-sig produces something (which I suspect it
will), it's more complicated -- you could have JAR-like files with
hierarchies inside.

1.b) Installation is the domain of the distutils-sig. I seem to remember
Greg Ward saying something about installing packages.

Yes. But this is no worse then the current situation, where people pick 
a toplevel name <wink>. I agree a registration mechanism would be helpful.

Personally, I *hate* the Java mechanism -- see Stallman's position on why
GNU Java packages use gnu.* rather then org.gnu.* for some of the reasons.
I really, really, like the Perl mechanism, and I think we would do well
to think if something like that wouldn't suit us, with minor
modifications. (Remember that lwall copied the Pythonic module mechanism, 
so Perl and Python modules are quite similar)

I agree. That's why I pushed out the straw-man proposal.
