I would certainly suggest that the use of multicast (if it eventuated) would probably be best as default off type situation where it
is enabled only by those wanting it and prepared to ensure their LAN's will comply and oblige.
People may well want to specify particular multicast (range) addresses to use.
I had posted earlier how I had successfully tested multicasting a DVD, the string I used specified 18.104.22.168. Its since been
pointed out to me (elsewheres) that this address is reserved, (see http://www.iana.org/assignments/multicast-addresses/) so I'll
probably change my testing to use 239.255.x.x, - a small point for anyone else considering trying this.
