Announce Core MIDI virtual port via Bonjour on OS X

Question

I wrote an iOS app a while ago which was receiving and sending MIDI commands over the network. All I needed to do was to create a virtual MIDI port which then showed up as connectable node in Audio-MIDI Setup of all Macs on the local network automatically. Meaning that it was automatically advertised as a service via Bonjour.

I now tried to do the same on OS X but I unfortunately my virtual MIDI port won't show up on the network computer's Audio-MIDI Setup. Can anyone give me a hint on how to setup a Bonjour service so that my virtual MIDI port is published across the network?

I tried the CocoaEcho example project and modified the code to announce a NSNetService like so:

[[NSNetService alloc] initWithDomain:@"local"
                                type:@"_apple-midi._udp."
                                name:@"" port:(int) self.port];

and announcing the service seems to work (it shows up in Audio-MIDI Setup). However, I don't know how to proceed from here as connecting to my newly published MIDI port doesn't call any of the installed callbacks.

Thanks!
