I added a request in the feedback center - add [RSS] token to Listing.Header and Listing.Footer - that I think would go a long way toward allowing us to create our own templates that integrate mapping.
Right now, I am using PA for a database of soccer fields and I modified the RSS template to include coordinates in georss tags. This made it really easy to include a link to a map of all the fields by just appending ?mapurl= to the Bing Maps URL.
I could make this even more dynamic and interactive by having the RSS token available in the header and footer of the listings. This would allow me to easily put a dynamic map in the header and/or footer of the listings that shows a map of the currently displayed list of fields.
Scott, how's it looking to get the RSS token in the header and footer of the listings?
