You could have a look at this - https://github.com/DonaldMcC/gdms/blob/master/views/default/user.html
It integrates a javascript geolocation plugin to web2py user registration and also Leonel Camara's excellent plugin_location_picker which together allowed me to do everything I was wanting to do. Only downside seems to be that I think you now need to provide payment details to use Google geolocation API's for the mapping piece and address lookup piece - however it is still free for light to moderate use on published websites.
