No Method for Unbroadcast Service (i.e. device-info)

[SJ_UnderWater]

As far as I can tell, there is no method for registering a service which doesn't broadcast, like device-info. According to the DNS-SD types list, DI is reserved, and Mac devices don't broadcast it, but respond to inquiries instead. For compliance with the (emerging) standard, this is probably necessary. There may be other services in the future which are resolved in a callback style without cluttering the local services list.
