The rtp-session module creates a media session that is announced with avahi/mDNS/Bonjour.

Other machines on the network that run a compatible session will see each other and will be able to send audio/midi between each other.

The session setup is based on apple-midi and is compatible with apple-midi when the session is using midi.
