Thanks!  I'm very interested in this facility.  I used it quite a bit 
with the pre-3.2.x Merlin releases.  Great potential.  Along with the 
HTTP facility, I'm motivated to help get this ready.

A trait some of us (like me) have yet to get a grasp on...

I like the use of commons-messenger.  It made for a simple interface to 
implement in order to build a message-driven component.  In fact, with 
commons-messenger, you don't have to know much about the JMS api at all. 
  Simple from the component developer's view point.  A definite plus in 
my book.

I've got some things I can probably contribute as examples as well, 
since I played with it a few months ago.

Yep.  We have a nice set of facilities shaping up that ought to give us 
the foundation to build a application server if that is your fancy.
