Good news!

I don't know if your dataflow library can support selectivly disconnects.
As you wrote in your previous email - one consumer can be connected to multiple
producers. If we can associate the boost::signal::connection with the invokation of
consumers operator() we could establish a selectively disconnect. At least I think it could work this way - but I don't know if it could be supported by your implementation.
What do you think?
