Have you checked out RunAs Radio lately?
Since 2007, RunAs Radio has been producing podcasts for Microsoft-centric IT Professionals and over the last few weeks has produced episodes featuring some of my favorite industry collegues - Ed Horley and Stephen Rose. On 3/30/11, Ed Horley discussed the current state of the transition from IPv4 to IPv6 and on 3/23/11, Stephen covers Windows vNext, IE9 and Intune.
Here are a few other older podcasts from some others I know in the Microsoft technology space that you might enjoy.
