<br><br>I guess you could set up a table that contains a cross product of all the nodes, along with the routes between them and the relative costs. This could get very, very large though.<br><br>Also, you'd have to build some logic to extract the portions of the lines between the start/destination points on the line and the nodes at the start/end of the shortest route.
<br><br>You'd probably want to use a few different weighting mechanisms too: distance, speed, fewest left turns, etc.<br><br>This feature isn't of huge use to me, but I think it should be high on the wishlist.<br><br>Jason
