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:

code that generates it:
