That is going to be the sticker.  Everything I've seen like this is 
either Java
or .NET.  The concept of "grid" or "distributed" usually implies
"cross-platform."

Of course, because you messaging fabric is Java doesn't mean your 
client has to
be.  xmlBlaster provides a socket protocol, IIOP (corba), and XML-RPC methods
for dispatching messages and registering callbacks.
