Portable Firefox OS X

I've packaged a Mac OS X version using this script so you can launch it with a double click from any device:

#!/bin/sh
here="`dirname \"$0\"`"
echo "Starting Firefox from '$here'."
echo "Wait a while before Firefox start."
sh "$here/app/Firefox.app/Contents/MacOS/firefox" -profile "$here/profile"
echo "Done!"
echo "When finish, quit Terminal.app before eject your portable device."

English and Italian versions are available here:

I hope in some more expert users help me to relese also other OS X portable applications like OpenOffice, Thunderbird, Nvu, NeoOffice, Abiword, Adium...
