Crossfader

Scoble teases about Crossfader which seemed to be owned by Microsoft and is creating a lot of buzz/hype even without any real details, some people are even wondering if this is Microsoft's entry into the podcasting world?

What I find even more interesting here is not that Microsoft is going may be entering into the podcasting world, is that on the Crossfader website, the title bar says 'Arriving In Miami'. Why is that so interesting about that? Because Dave Winer has been spending a lot of time in Miami lately, is he involved in Crossfader?
