[Zope] multipart pushing

[Ragnar Beer]

Howdy Zopistas!

I'd like to implement a chat function using the multipart content type and I
wonder if that is possible with Zope. My idea is to write a python script that
pushes the content of a database until e.g. the stop button is pressed in the
Browser. But how would the script know that it's supposed to stop? And would
such a longtime connection completely occupy one Zope thread so that I'd have
to increase the number of threads?
