Add full path to title bar of Finder

Very simple, from the terminal:

defaults write com.apple.finder _FXShowPosixPathInTitle -bool YES

Then in the terminal, to affect the change in your open Finder windows:

killall Finder

To revert, change YES to NO

(Btw, you can have a more UI oriented path shown by choosing View|Show Path Bar for the Finder but I find it easier to view the path in the title bar since I spend a lot of time in *nix)

This works in 10.6.6 but I'm not sure what other OSX versions it works on.
