I'm using Debian.  I've already had to switch from the
"netcat-traditional" package to the "netcat-openbsd" package.
Debian does already include that patch, but what a mess...

Since already know libvirtd is installed on the remote host,
would it make sense to just add a new set of options:
      libvirtd --socket-connect
      libvirtd --socket-connect-ro
that do the same thing as "nc -U" on the appropriate socket?
Then we know it would work everywhere, and have the added 
benefit that the client wouldn't need to know the location of the
socket.
