Thanks for your help.

I was thinking that the interceptors might be a good idea. I like the idea
of the 
responsibility being in the broker because, you could argue, it is the
broker and 
not the client that should concern itself with HA and load balancing etc.

The Transformer on the Producer sounds quite clean but it still assumes the
takes responsibilty.

 I really like the idea of Camel. I was reading about the EIP's the other
day. I'm afraid 
I probably haven't understood its purpose properly. I thought it was a
of recommended patterns which Active actually implements. Are you saying
I can specifically get Active to use some of those patterns? Sorry - a bit
thick here.

Thanks again.
