Ding!  That reminds me, there are some vendors/libraries out there where  
you can obtain tables that map zip codes centroids to lat/long data. 
  
I even have a table of zipcode, state, postoffice, latitude, longitude.  I
don't feel like looking at my notes as to the source, but if you want it,
you can have it.
