gpsdX is an open-source GPS daemon, which allows you to share data from a single GPS source with multiple applications on one or multiple computers. Not only can it reproduce raw GPS data to an unlimited number of clients, but it can also provide fully parsed, on-demand GPS information to any client program.
gpsdX is a Mac OS X native, Universal Binary build of GPSd. It comes complete with an installer and a GUI configuration utility to set it up to launch when you start your system.
