Mapeed.AddressChooser is a Javascript script for creating an address form with a twist: it displays the address mentioned in Google Maps (can be used with another map provider by creating  your mapping proxy) in real-time.

Ajax Google Maps

The script adds a behavior on HTML form, & doesn’t generate HTML markup.

It can also be plugged on any existing forms.

You can focus the map to the user’s city/country with the IP used (if mapping provider supports).

Mapeed.AddressChooser is well documented & has a nice demo with script.aculo.us autocomplete.
