I like this idea. It's simple and it's something I've implemented (and 
seen implemented) dozens of times.

I have a little more trouble with this idea, for a number of reasons:
  * Address formats vary from region to region.
  * Sites usually want items like the postal code, state, county or town 
separated from the street address for various reasons. This is not 
catered for by your proposal.
  * To do anything special for this field beyond just displaying a big 
text box some sort of external data source is required, but it is not at 
all obvious what that data source would be or what a good UI for this 
field type might be.

I have similar reservations about this one, but at least there is a more 
obvious UI: mobile devices with built in GPS recievers could concievably 
provide an option to fill in the current coordinates.

However, I'm not sure that submitting geographic coordinates is a common 
enough case to warrant an input type of its own. Part of me wants to 
generalize it to be type="2dvector" and type="3dvector", which can then 
represent any 2D or 3D coordinates. I'm not really sure what a UA would 
do to such a field that would be any more useful than two or three 
type="text" elements, though.
