Countdown to PDC2008:  What are the platform infrastructure details behind the Mesh technologies?  Corporate Vice President of Live Platform Services, David Treadwell, will be spilling all the beans in his PDC keynote in just a few weeks, but in this Q&A he gives us a sneak peek.  David explains how there’s so much more to Mesh than just the user experience, and how he and his team will be revealing the underlying particulars that fall below the line at PDC – the platform infrastructure that helps developers build stellar Software + Services apps.  And did Treadwell mention bits that will be given out at the PDC?   We think he did, but you gotta listen to find out more about what the PDC team affectionately calls the "goods."
