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,
