[Zope] any streaming audio formats that Zope can serve?

[Anthony Baxter]

Playing with some Zope stuff that serves up a .wav file (dynamic sound 
content, mmm) it occurs to me that it would be nice to be able to have
some sort of streamed content (so that the end system starts playing 
before it's fully downloaded the file)

Are there any "streaming" type audio formats that don't require a special
server? Then Zope could just deliver this to ZServer (or Apache) and let it
stream the data to the end system.

Obviously the format also should have a reasonably available client...
