Last time i looked at how the Wikipedia layer worked: when the user hovers the mouse over a map-tile, a request is sent to load the "hit areas" for that map tile. That allows the mouse-cursor to change when it's over a hit-area, and for a "hit" to be detected when the map is clicked (kicking off the request). > I think file based output would be the easiest solution because it can > be read by any text editor.

(ideally a JSONP-style file with a pre-specified callback so it can be used cross-domain, but we can sort out those details later). Once you have the json files and rendered map tiles then the client has everything it needs.
