For the future, this is pretty simple code to write. All you need is the
longitude and latitude of each zip and there are several databases with this
info on the web. After you have that, the formula for calculating the
distance is pretty straight forward, especially if the database is in a SQL
server. The formula we use is accurate for zip within 1500 miles since we
did not add the cosign for the curvature of the earth.

I may have found one that will work. If anyone is intersted, this one
seems like a decent solution:

Subject: Looking for a zipcode web service
I am looking for a web service in which I can pass a zipcode and a
radius distance in miles and return all zipcodes within that radius.
I have searched on www.xmethods.com and found some that will return
distances between zips, but will not do exactly what I am looking for.
Is anyone aware if one exists?
Thanks,
~Dave
