Hello, I just uploaded a new version of "Channel" at http://channel.sourceforge.net. Channel is a C++ template framework for distributed message passing and event dispatching. Channel is built for boost and depend solely on boost facilities. This release introduced associative lookup based name-matching and message passing. 2 kinds are implemented: . regex based name-matching is implemented using Boost.Regex. applications can use regex patterns to subscribe to messages, e.g. use regex(".*ball.*") to subscribe to messages sent for "basketball", "baseball",etc. . Linda style tuple associative lookup, implemented using Boost.Tuple. For example, we can use tuple ("Adam","Smith","Male","Math Dept") to identify a person; application can use (wildcard, wildcard, wildcard, "Math Dept") to subscribe to messages for all persons in math department. Examples are added to demo these 2 methods. The design document is also updated; i tried to clarify main design idea; sections are added to clarify class concepts and explain how to extend the framework by adding new id_type , id_trait and new dispatchers. Corrections, comments and suggestions are highly appreciated. Happy holiday! yigong
