Well, i WAS looking at possible ways to do this, but unfortunatley, google doesn't allow you to just drop in a Zip code, so you'd have to have the user input their latitude/longitude which is well beyond most...
There are sites which allow you to triangulate a zipcode to a lat/long but they only allow so many queries per day, and on a site with over 100 members you'd easily reach this limit on a few runs of even cached data...
