I was not talking about doing a monkey patch there, but add a feature
within the publisher.

they are two distinctive part to do that:
1/the client side, wich gets asynchronous feedback from the server, that
2/ the server side that keep track of a given request state. (getting
data / processing)
(that's the missing part, that you probably did with another cgi
server on seperate thread)
