For a Java project at work, I've been using JmDNS to enable service discovery over a LAN: <http://jmdns.sourceforge.net/> Since it's pure Java it works on MacOSX, Windows and Linux.

Through process communication, you could manage a Java process running a LiveCodeHelper class that takes care of the registration and discovery of services.

When I find the time, I'll write up a blog post...
