I've spent time trying to make this code more flexible with other types
of relays, e.g. socat which can be invoked with

socat - GOPEN:sockname LIBVIRTD_PRIV_UNIX_SOCKET

but haven't come up with anything I would consider upstreamable.  Jonas
Eriksson also made a brave attempt [1] :-).  Any suggestions for
improving this code to handle other relays at runtime?

Jim
