Maybe you guys should take a step back and look at what you are 
saying.  You have one person with a $200-$400 GPS receiver recording 
a track which then is hand edited to add to an open source map.  This 
track disagrees with aerial imagery that companies have spent 
millions or even billions of $$$ to collect, process and 
provide.  Now you are thinking of telling a distributor of that data, 
based on your single track of collected data, that they need to 
"correct" their data.

Do you really think they are going to take you seriously?  Perhaps 
you are thinking of the Yahoo imagery as if it were a collaborative 
effort like OSM?
