I need to allow travelers to use google maps to plot a route, and then query my database of points of interest (let\'s say, McDonald\'s locations) and then show all of these

Check this out

http://google-maps-utility-library-v3.googlecode.com/svn/tags/routeboxer/1.0/examples/routeboxer-v3.html

Here's the documentation: http://google-maps-utility-library-v3.googlecode.com/svn/tags/routeboxer/1.0/docs/examples.html

You could get the box coordinates from RouteBoxer and send that to a serverside script for processing
