Reverse geocoding is just a spatial search. You need data, for the US, you can use Tiger data from the Census or other spatial data for your coverage area. And you need a way to do a spatial query. This can be done using Postgresql and PostGIS or using Mapserver.org. If you want to license a solution, checkout http://imaptools.com/ (my consulting site). Getting good data probably presents one of the biggest challenges depending on your coverage needs.
