  It's rather LAN oriented, I need first to find the ports of the 
QEmu instances (plural, if you limit to one per box, then you can block the
default port number and there would be no problem) on a local machine. I
don't think that "Multicast DNS"/RendezVous works with random port numbers,
all it does over normal TCP is scan for local hosts without using DNS
resolution. Again I don't think it's really the problem I'm trying to solve,
maybe I just didn't expressed myself clearly :-)
