I always feel a bit guilty about the amount of stuff we do via the MS Architect community for Infrastructure architects as oppossed for the Strategic and Solutions lot.
The excellent Mr Nathan Mercer, just back from his gig in Singapore, is holding a series of unplugged sessions up and down the country later this month through early October. These are more technically focused than our Architect forums - Nathan always does a great job of communicating new technologies and what they are good for. I think Nathan should pay me for saying such nice things about him even if they are all truthful - if you go any of these sessions which I highly recommend I think you should tell him that :)
