Just something like this would be fine,
To use multicast(4), add the following line to /etc/rc.conf.local:
multicast_host=YES
since a big part of liveMedia's heritage was to provide multicast
support, and also because several of the things in the base OS which
use multicast don't actually need this to be set, I think it's worth
a quick mention.
Anyway this can be added afterwards so I am OK with your diff.
