do you mean HTTP streaming? http://ajaxpatterns.org/HTTP_Streaming

I recently noticed something that makes it tricky to use zope3 in 
conjunction with Ajax: the request ID computed from the browser via a 
standard HTTP request/response pattern is different from the id obtain 
with XMLHttpRequest calls - which makes it rather tricky to use zope3 
session id with Ajax (the same browser is seen as 2 different browsers).

maybe setting up a page on the z3 wiki that lists current "issues" with 
Ajax could be a good start?
