Ok, so an immediate applcation of this would be to write a small app that simply browses the local net for all services of a given type. Might be interesting to find out, who has personal File Sharing or (worse) Printer Sharing turned on. But where can I find the service types for Apples built-in Services? Where can I find any Service types. Maybe _rce._tcp conflicts with the service of an app called "Really Cool Editor"? Thanks anyway for the enlightening article. Armin

  Howdy,
  
  I should have mentioned this in the article, but there are many common service types that are publicly known. If you look in the file /etc/services you will see the names of the "well known" services. This file shows the service name and protocol, which you can put together into a service type: _name._protocol.
  
  I suppose there is always the possibility of conflicting service types, and fortunately the worst thing that can happen is that your app can't connect to a service advertised with the same type name, yet really a different service (sure, this isn't really a trivial thing, but I believe the chances of conflicts are pretty low). Application designers can also give more unique service names, such as _mikebeam_rce._tcp.
  
  About a browsing application, there is code for a service publisher/browser pair of apps that you get in the open source Rendezvous package that I mentioned in the article.
  
  Hope that clears things up...
