I would assume that the daemon that runs the /uri filesystem would check
signatures on downloads.  I don't think it does yet but there is no
reason that it couldn't.  Some effort would be necessary to set up a web
of trust so that the user didn't have to decide if the keys were valid. 

I believe that the zero-install system actually downloads the contents
of directories as tarballs, so the could just sign the tarball for each
release.  I don't really see how that is any worse than what rpm

There is already a per user daemon in the system responsible for
displaying download progress bars and stuff.  If the signature checking
failed it could present the user with a nice dialog saying that the
software couldn't be run.
