Shalom It's looking like Matthew Bentley's colony container -- http://plflib.org -- is going to pass over Boost on it's way to the standard. I've added serialization support for this container to the C++ Middleware Writer and added some code that tests that support to my repo -- https://bitbucket.org/webenezer/onwards . I enjoyed Jon Kalb's CppChat show where he talked to Matthew about this container -- http://www.slashslash.info/cppchat/ https://www.youtube.com/watch?v=SFAJ238rBNw -- Brian Ebenezer Enterprises - In G-d we trust. http://webEbenezer.net
