How Hard Could This Be To Script?

Okay, this should be a piece of cake for some experienced AppleScripter.
Apple’s Address Book allows you to MapQuest any address. What I would like is an Applescript that will take addresses from two selected cards and do the MapQuest “directions to” map. See
That’s all. Is anybody able to do that?

Since I’m an AppleScript newbie, It took me a few hours, but I actually wrote this awesomely useful script!!!

My next question is, I think a lot of people would like to have this functionality of Address Book, so what’s the best way to make the script available to everybody?

I put this online. Please check it out and give me suggestions for improvements.
