How to reverse geocode without Google?

Reverse Geocoding

Reverse Geocoding Problem Overview

Are there any web services (paid or free) out there besides the Google Maps API which allow you to reverse geocode?

My particular application will have access to a latitude and longitude and I need to be able to get the US Zip Code or State.

The reason I can't use Google is that the Terms of Service seems to indicate that if you use Google Maps API, you need to use the data to display a Google map.

I am using C# .Net framework in case that's relevant.
