I don't see the rationale for making the source the primary key and the
channels the secondary keys.  I think apps will more likely know the
channel (DNS name) and want a listing of servers.

Have you considered using some variation of SRV records so that you can
specify port numbers per server?  Depending on how you do it, this would
eliminate the need for a magic ".mcast." in the hostname.
