Don't forget there are *two* points for centralizing test control code. 
One is the co-ordinator, the other is the test runners that will 
actually be running the tests.  The tests themselves should be straight 
JUnit/CppUnit tests but the test runners can intervene pre- and  post-  
each test, they can collect failures, communicate with coordinator etc. 
Things that are more appropriate to do in the client address space can 
be done in the test runners. I don't have specific items in mind its 
just a general observation.

The only thing that has to be done *within* the tests is handling 
timeouts based on message traffic, and I think even that should hidden 
in the test setup code. It should be trivial to add an extension point 
in each qpid client library to run a callback for each message 
sent/received. We can use it right now to measure timeouts for tests, 
and if done right it will be useful for all sorts of other "frameworky" 
things in future - capturing management information, logging, debugging 
etc.  I feel an interceptor pattern coming on :)
