Adding ZIP-to-district look-up

Hey, a bunch of neat web sites have a neat-o feature where you can enter in your nine-digit ZIP and find out your congressional district. I put one on my blog, cannibalizing the one on Congresspedia. However, I used Project Vote Smart's results, because I think they are more complete.

I hope to put a widget on my blog to make adding this to your own blog a one-step process.
