Hi all, There is such a thing in z3! Or at least in the "new" zope3.org implemnetation ;-)
I remember that Uwe Oestermeier was developing something like a livepage which can receive and send streams of HTML on a open request. See this for more information, but don't ask me if it's working. http://svn.zope.org/zope3org/trunk/src/zorg/live/README.txt?rev=66712&view=m arkup Please contact Uwe Oestermeier if you have questions. I guess you can find his address somewhere at the sprint announcment list. He was organizing the Isar Sprint. Hope that's usefull.
