I think we talking almost about the same thing here.  As I said previously, I made a small prototype which behave quite nicely for what I test.  It has both a timeout that it propagates down the stream, and also propagate an end message upstream after it consider everything is finish.  I used only XREP/XREQ sockets for this but that's only because that's the only way I know to access individual downstream connection.

It is still in early stage and probably can be better done.  It's the first time I used a ROUTER/ROUTER device out of an LRU queue, so I've certainly overseen some issues, especially in regards to message queues on timeout/error.  But the code is here:
