Since the remote system has to have the libvirt daemon installed already,
we could simply ship a mini 'nc' program of our own - libvirtd-cat ? The 
main problem with this would be getting dealing with back-compat. Should
the client try 'nc' first, or ty 'libvirtd-cat' first. Or we could see
if Debian netcat maintainer is interested in a patch to add '-U' support
to their version
