Can automatically detect a network location based on a rule, like a DHCP packet received or an airport network name

Mobilizer takes Mac OSX Locations to the next Level.
It can automatically detect a network location based on a rule, like a DHCP packet received or an airport network name.
Once that network is detected it changes the Mac OS X Location, especially useful if you use proxy servers.
It can then run actions, which can connect your network shares for you and remember the username and password for those shares or set your default printer.
You can now select a location from a location menu anytime, by pressing Alt-Option-L.
