I didn't know this was available as of today, as it thought it was for a future release. You can now do searches on MSN.com and get the results sent to you via a rss feed once you subscibe to the rss feed. Try it out at www.msn.com. Do a search on "MSDN Webcast" or MSDN Architecture Webcast" and subscribe the rss feed option at the bottom of the page. It's pretty cool.
