At Songza, we purchase the MaxMind database for doing geolocation based 
on IP address.  This is how we enforce our content licenses which only 
allow us to stream music to the US and Canada.  We also use it to target 
specific features (or advertising) to specific cities or other 
geographic areas within the US and Canada.

That being said, we understand that it is only an approximate solution.  
It is useful, but not perfect.  If you go to the MaxMind web site, you 
will see they have a range of products, at different prices, which 
promise various levels of accuracy and error rates.  But none of them, 
for any amount of money, offers "resolution down to the street address 
and 0% error rate".
