The only definitive answer on this type of license usage would come from contacting mailto://maplic@microsoft.com

I know a couple clients who have requested this usage and were approved almost immediately by MS. Just so long as they don't publish map images, POI data, etc. Information on calculated route distances and calculated directions seems to be okay with MS.

That being said, your "interesting waypoints" would have to be public domain or self-input. Other than that, you should be able to get approval.

I'd be happy to share some VB6 COM code with you to get you started.

You might also want to check out the MapQuest API and Virtual Earth API, since these are well-suited to your task and absolutely available for this usage.
