I wrote up this little script that will display your ip in a text box, and gives you the option to click either cancel (if you just wanted to know) or click copy text (if you wanted to give it to your friends).
I think this simple script should help the Mac users out there give their IP to their friends if they want to play Halo.
I know you can just go to the website, but this makes it a bit easier.
Picture (#s cut so you don't know mine =P):
Have fun.
