Ah, thanks.

Unfortunately, the SSH port is bound only to the loopback interface
(so that others on my LAN cannot access it). As such, I need to
register the service as being on localhost rather than
mymachine.local, as per the following:

$ dns-sd -P ServiceName _http._tcp . <port> localhost 127.0.0.1

However, the Bonjour key (which I set to "http" as the SockServiceName
is 0) causes it to be registered as being on mymachine.local. Can I do
anything about this?

Thanks,
Hamish
