 From the appearances of the examples at <http://www.videolan.org/doc/ 
streaming-howto/en/ch04.html> VLC uses UDP for this, as I described.

EG:
   % vlc -vvv input_stream --sout '#duplicate{dst=
   standard{access=udp,mux=ts,dst=239.255.12.42,sap,name="TestStream"},
   dst=standard{access=udp,mux=ts,dst=192.168.1.2}}'

Ummm, is Myth's code already based upon VLC? If not it's likely to be  
easier just to add multicast into Myth. If Myth already uses UDP (??)  
then that really shouldn't be too hard for a decent programmer  
(although I'm afraid I don't meet that description myself). For me a  
more opaque problem is how to tell the two front ends to play the  
same thing.
