Mapping my contacts

This, rather than me sharing something amazing with the world, is actually more of a rant / feature request.  I have just spent some time searching the interweb for a contacts address book application that displays all my contacts on a map, allowing you to see graphically where everyone is.  Sure, there are plugins and stuff that allow me to click someone’s address and have a map pop up showing where that one person lives, but it would be really fascinating to just show a map of where everyone is, all at the same time.  So far, no one seems to have done this.  Maybe it’s just that I’m the only person who might possibly find this interesting or at all useful, but I’d have thought what with the Google Maps API available someone would have done this by now!  Surely it can’t be all that difficult, especially since you can overlay custom content onto a Google Map.  Is it really that much of a stretch to ask for someone to embed a Google Map into an address book application and link it into the addresses stored for people?  If anyone has found anything that matches my hazy description, do let me know!  Even if I don’t end up using it, it would be interesting to know if something like this exists.

Of course, the obvious solution is that I actually sit down and write the application myself, but that involves programming, and I swore never to do that again after I finished my degree…
