Hi,
I posted last night's audio here: http://www.robertplevy.net/boston-lisp/
Also, I have put up a basic xml feed using xml-emitter in Common Lisp. I have verified that it works in bashpodder, google reader, and opera's feed reader (probably works in the other applications too):
feed: http://www.robertplevy.net/boston-lisp/boston-lisp-podcast.xml
code that generates it: http://www.robertplevy.net/boston-lisp/boston-lisp-podcast.lisp
