Greg,

Thanks for your note.  The QMFv2 documentation desperately needs 
updating.  The one wiki page that has been kept up-to-date is the 
protocol page 
(https://cwiki.apache.org/confluence/display/qpid/QMF+Map+Message+Protocol).  
Real documentation will go into the new DocBook content under SVN.

The status of the project is as follows:

The new QMFv2 implementation is committed on trunk at 
qpid/cpp/{include,src}/qmf.  The "engine" subdirectory in that area will 
be deprecated and is not used in QMFv2.  This implementation is written 
in C++ and uses the same API pattern that is used in the new, ABI-stable 
messaging interface (qpid/cpp/include/qpid/messaging).

The strategy for multi-language support for QMFv2 is to provide bindings 
in other languages to the C++ implementation.  Bindings for Python and 
Ruby can be found in qpid/cpp/bindings/qmf2.  There are two agent 
examples in qpid/cpp/bindings/qmf2/examples.

A set of system tests (that run consoles and agents of various languages 
against each other) has yet to be committed to SVN but is in 
development.  The libraries are in a usable state, though not complete, 
and it would be great if you were to try them out.  If you do, please be 
encouraged to ask questions and provide feedback on this list and/or on 
dev@qpid.apache.org.

Regards,

-Ted
