In case you missed us at PDC 2008, you can see the Virtual Earth Deep Dive Session  on the web:

Here's a description of the session:

Learn about the next major release of Virtual Earth. See the improvements to our parsing and geo-coding engines, clustering, localization, and routing. Hear how the new Virtual Earth Web Services provide server-side support for building location-based applications on desktops and mobile devices.

You can also download the Powerpoint Slides and Sample Code from the session.
