I just found this web page that talks about a free API that could be used on a web page to do address lookup/geocode as well as map to the proper census tract and/or census block. I'm not a programmer but maybe someone on the list could look at this and put together something that could be used. Ideally it would do both single and batch lookups. If there is a way to also standardize the address fields to increase the accuracy that would be a big plus.
