I've often wondered what the copyright situation would be for crawling the web,
finding pages with a geocoded link to Multimap/Streetmap/whoever, and parsing
the result.

For example, if you've got a page that contains:

Visit us at Fred's Electrical Store, High Street West, Uppingham, Rutland LE15
6AB, or <a href="http://www.mapsite.com/easting=340000&northing=450000">click
here for map</a>

...then you know (a) where LE15 6AB is, (b) where there's a Fred's Electrical
Store, and (c) that LE15 6AB is associated with "High Street West, Uppingham,

The parsing would be quite hairy, but not impossible. Shame Google doesn't let
you search by regex...
