If you're talking about packaging the components in a shared library, yes - at one point I put together an example that shows how to package a shared component using the Extension library: I think I was being a bit ambitious. What I was thinking, is possibly a source forge project (or sandbox/wherever) which had boost::dataflow components that people had written, and had decided to share. My experience in this area comes from gstreamer (gstreamer.freedesktop.org) which provides a library similar to boost::dataflow, but also provides libraries of componets for multimedia processing. My previous example was probably a poor one, because it would be better implemented in boost::gil. But if there were a library maintained of sources, components, and sinks. It would be helpful. It is likely that this would become a project on its own however. Maybe you could list GStreamer in your "Support for more layers" section of the documentation. I don't know if it would be something I would be capable of, if it makes sense, or how feasible it would be.

I am currently rewriting dataflow, and my first major goal is to have a dataflow system that makes extensive use of such libraries of components.
Best,
Stjepan Thank you for you terrific work.
