there is currently no widget that does this.  The Locate widget 
specifically uses web services that provide a lookup API (and the 
services that it currently implements are all for Canadian stuff).

I do not believe that there are any plans to implement a widget of this 
kind, although it would probably not be too difficult and it would be 
kind of cool.
