Walter that's another story, that would be best to discuss at the mailing list, so more people can get involved.
You would need a strategy for how to correlate the replies, which must be part of the protocol. So the end user must have a way of telling the camel-mina how it should correlate replies with the request messages.
And the camel-mina component need to have logic where it stackup requests, and accepts incoming replies, and correlate those. And it may have to handle timeout, and unknown replies coming back etc. All kinda of logic we already have in the camel-jms, so its possible.
