Here's another view using the Virtual Earth polyline functionality with pushpins for the start and stop points. You can see where Spike and I met up for our morning carpool commute (where the green line veers off to the left).
I plan to create a screencast video of the sample project in the near future plus some other ASP.NET AJAX code I've been playing around with. In the meantime, if you're interested in the source code for the mobile device application that talks with a bluetooth GPS device, the Web Service (and associated database) as well as the ASP.NET AJAX code that calls the Web Service and handles the mapping you can download it below. You'll also find some additional ASP.NET AJAX demos in the zip file including:
- Using the UpdatePanel with Triggers and the PageRequestManager
- Calling Web Services using XML Script
