Do you mean using Camel routes as a proxy to some service (kinda like

you can do this using the CamelProxyFactoryBean

Or do you mean you want to use Camel purely as an interceptor - called
before the bean is actually called to fire off some arbitrary messages
etc? Kinda like a POJO version of a wire tap

Yeah - I think you just want to create a proxy to the POJO as
described above - this creates the client side stub which would send
the message to some endpoint/route. Then on the server side you'd
consume from some queue and route to the Spring POJO

Yeah - right now you either use a client side proxy to fire a message
route; then on the server you consume messages and bind them to POJOs.

We could also add an interceptor which just sends a message to camel
before actually invoking a POJO method.
