Like Brian, I am straying dangerously close to a precipice of 
ignorance here, but to make Zope capable of true streaming you'ld 
probably want to implement the Realtime Transport Protocol ( 
http://www.ietf.org/html.charters/avt-charter.html ). A good overview 
(with a QuickTime emphasis) can be found at
http://developer.apple.com/techpubs/quicktime/qtdevdocs/REF/Streaming.htm

Apple's streaming RTP server software is open source (Darwin) and 
people are porting it to Linux.

As Brian suggests, for the moment it's probably best to simply link 
to the streaming media.

Cheers,

Michael
