Thanks for everyone that replied to the query for interest on a "signal flow" library. I have started incorporating the feedback and expanding the documentation into a more formalized notion of a Signal Network library, which I would like to propose for Google Summer of Code / Boost. http://dancinghacker.com/code/signet/ holds a draft of the proposal/documentation - the current implementation with examples/tests is available for download from that page. It should work with both Boost.Signals and Frank's thread_safe_signals (thanks for that patch Frank it worked) for the most part. Some of the improvements are: * better choice of operators / syntax * modular components for storage and flow control of signals * started implementing support for threading * prototype of a predefined topology (chain) * ... and more.... If you have any comments / requests / suggestions on the proposal and/or the library, please send me a note (or feel free to post requests on the SoC wiki :-) ) Thanks, Stjepan
