Hi Mark, we have loooked into this before with some countries, so that when for example you would click on the state , it would open up another map of that particular state and its cities mapped out.
Its not "difficult" to do but the time involved in such a project is simply astounding.. we do have a state map -
http://www.bilekas.com/usa which has the ability to dropdown when the state is clicked, what we intend to do is have the drop down contain a list of all the cities in the state, rather than a map!
