Thanks Alan, but finally I got it working without pipes, but with a queue. I was afraid of getting into a new world, but it turned out to be easier than I thought. OTOH, I am really not comfortable with MVC; I am using some MVC patterns as I don't have the choice, but I still can't really understand the concepts. But it's another point... Thanks again, Tiago. _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
