It sounds rather like you need a streetmap of each city, where you can colour streets say red for "already chosen by someone else" and green for "choose me if you like" ? Or is it okay if user's choices have common segments A-B-C-D , X-B-C-Y ?
I would suggest tile overlays as the best way to implement that visually. Users clicks could be sent back to your server to identify the selected street and check if still available. I would suggest abusing Google's directions service to obtain a full set of city streets is not the best way, you might look at OpenStreetMap for data sources. -- You received this message because you are subscribed to the Google Groups "Google Maps JavaScript API v3" group.
