MapPoint in MSDN Magazine
The December issue of MSDN magazine includes a brief interview with Steve Lombardi and another article providing an overview of Microsoft's public XML web services including MapPoint.
The talk with Steve Lombardi is in the trailing article just inside the back cover. Highlights include the annoucement that Microsoft Location Server will become available in early 2004 and some stat's regarding usage of the MapPoint Web Service.
An article about web services from Microsoft devotes a couple pages to MapPoint including code samples and pointers to resources.
