Chris, Sorry, I did not get around to implementing os geocoders. Here are some links I came across, however:
http://www.ontok.com/geocode/compare http://www.ontok.com/api http://geocoder.us/ One possible alternative is to find the code for a geocoder and use some of the free data that is available for it to operate on. I did not look into that route, but it seems there should be plenty of examples out there and tons of TIGER data. -Al
