NetworkLocation by Centrix.ca takes the location paradigm to a whole new level. Based on many criteria including AirPort network detection, peripheral connections, or even geographic location using the Skyhook Wireless system, NetworkLocation can automatically change your OS X network location, change your iChat [Messages], iTunes, or Mail settings, adjust keychain, screensaver, volume settings, and more. Of course, you can manually tell it which location you want to use and all of the settings will be updated in one fell swoop. This is a terrific time saver.
On the Dialectic online resources page (http://www.jonn8.com/dialectic/resources/), there is a free Dialectic plug-in for NetworkLocation 3+ that allows you to specify the Dialectic Location to use for each of your NetworkLocation locations.
