A couple of questions:

Do you think this level of layering is going to be necessary in the client?
It sounds flexible and extensible but if that flexibility is not put to good
use in practice, it may just add complexity. What is the use case for the

Do you think this level of layering might slow the client down? Getting from
the client API down to the wire looks like it is going to be a considerably
long chain of calls (another layer above for JMS, and Mina itself probably
