Google launching AdSense for Audio ??

There is a lot of buzz happening on this one.. when will they launch ??

Here's one source, via SEW:

<<How will they engage the market? You guessed it—it appears contextual placement of ads along side of podcasts. I would think they would focus on streaming media appearing on Web pages and, likely, RSS feeds… perhaps even within Google Reader?>>

Then this means that Google Reader may have an embedded audito/Mp3 player or am i misunderstanding this ?? That is, are Ad's being placed in the audio or alongside on streamed data ???

Contextual ad's alognside Podcast really does nto make sense!!
