Does anyone know of any "contacts mapping" software?
 

As a salesman, it would be incredibly useful if I could have an application that imports all my contacts from a spreadsheet of post-codes or full addresses into a map. Google Map or Google Earth would be ideal..

Anyone have, or know where I can get an application like that?

I have seen Business Map, but this is only for North America as far as I can tell.

Any tips most welcome!
