Looking at Yahoo! maps, it seems that they are (in some places) of 
sufficient resolution - just about -  to estimate field boundaries. I'd 
like to add something to the Freemap site to allow walkers to easily add 
field boundaries to OSM, as they are one of the most important aids to 
navigation on walkers' maps.

The question is then - what are the exact terms and conditions for using 
the Yahoo! maps in OSM? I seem to remember that as long as you used the 
Yahoo! api to access them and display the copyright message, it would be 

Whilst we're on the subject - what about a key/value pair? boundary=field?
