That was quick -- LongNow has the audio recording of Bruce's speech last Friday up already. You can download it in MP3, Ogg Vorbis, and FLAC formats, but beware -- these are not small files (the MP3 is 66MB, for example).
(Thanks for the heads-up, Stefan!)
Update: Zander Rose, of Long Now, says in the comments:
We are getting slammed with downloads right now (morning of 6/16). We are working on finding a larger pipe to serve this out of now...
