Name, Address, Phone number…..what's next on my address book. Is it maploc??

With the power and popularity of keyhole and region/map searches by google it appears we will soon have a next item in our address books. Lets call it by the name "maploc"(Or what ever u fancy). This maploc is a googlemap search relative locator information thats on your address book either on computer, pocket PC or whatever devise you have. On this locator you just click it, it will show the way to go from your own location. or you feed it to your gprs on your CAR it will show the nearest location on your GPRS screen. Whole set of common API to identify a persons location graphically. Definitely a cool thing to have
