I have been working on a framework that will allow multiple AMQP versions to be supported on the Java server - plans are also to do the same for the C++ server. This is not a trivial problem to solve, especially given how much work has already been done on the Java code-base. I have posted some design ideas for this on the Apache Qpid wiki (http://wiki.apache.org/qpid/AMQPVersion), and invite comment and discussion.
I propose that to make communications easier, we restrict the discussion to this mail list, rather than have the discussion in two places - the wiki and the list. I propose to keep the wiki updated every couple of days to reflect the latest thinking in this area. Thanks, Kim
