OK, as previously discussed (and promised) this has been pushed forward 
a little.  It sat in my head for quite a while until Javapolis in 
Antwerp on the 14th.  It was only when Rickard Öberg 
(http://roller.anthonyeden.com/page/rickard) gave his presentation (AOP 
EJB killer) that I felt galvanised into action.

This should be invisible for client side use as usual.  See 
SimpleAsyncTestCase forexample of use.

Still to do :

  * Ant task to allow specification of async methods.
  * Async properties (specialisation of async methods)
  * Over-JMS transport.

Regards,
