There have been a number of conversations within the forum regrading address geocoding.
While this is relatively simple to implement within an API a dedicated geocode component would be really useful.
This is in fact already implemented within the maps component albeit not in a form which can be accessed via events etc
(See adding static centre in google maps, it is auto geocoded when refresh clicked)
I see this component taking a google API key and an address string and returning the google API geocode results object
