Hi there, To those who are interested, i justy posted another snapshot of Channel - a boost based framework for distributed message passing and event dispatching at http://channel.sourceforge.net. The major changes are: 1. initial Windows build on WindowsXP with Visual C++ 2005 Express. Most library code and samples build, tested and worked correctly, with the exception of the sample using shared-memory. 2. write a simple wrapper to use Philipp Henkel's threadpool library ( http://threadpool.sourceforge.net) as executor, tested and worked smoothly. 3. reworked choice/join arbiters and implement them in both synchronous and asynchronous forms 4. add queues classes, add more documentation and fixed some bugs. Any comments and corrections are highly appreciated and they will help my boost proposal in near future. Thanks Yigong
