This all looks good to me.

Do you mean 'install' or 'install setuid'? If the former, then non-root
packagers are still going to want a way of installing those plugins, so
we still will need a 'make install-root' or some such eh?

I actually prefer the 'install setuid' option - always install everything,
and then make root plugins setuid if effective user is root. That does 
the right thing in the direct-install case, and makes life easy for 
packagers too.
