I think I see it better now. I think the _nssocketport._tcp you see is the NSSocketPort registered by the NSSocketPortNameService by the line you mentioned (NSSocketPortNameService underneath also advertises using bonjour). The _bdsk,_tcp is the NSNetService created on line 286 in -newNetServiceWithSharingName:. The first one is the named socket port that's used for clients to connect back to (using DO through NSConnection), and is created in a background thread. The second one advertises the service and the sharing name, and is searched for by NSNetseviceBrowser. Perhaps it would be possible to use a single service with a single port (in the background thread), but I'm not sure if that works with DO (I've certainly never seen sample code for that). I know too little about ports to know for sure if the port used by the netservice can be used for DO. The only thing I know for communicating over this port is directly passing data over the input/output streams, but that's too low-level.
