ServiceMix 4.0 is a big change compared to ServiceMix 3.x. We will still support JBI 1.0 of course, but we will leverage OSGi has much as possible. This means that the deployment unit will be mostly an OSGi bundle (instead of SU / SA). One of the building block of ServiceMix is also Camel which defines all the routing between endpoints. These routes are defined as jaxb2 pojos (hence xml too). So one feature that we need to add is to be able to apply a "transformation" layer on these routes (on the pojo or the xml model) to apply some aspects. Hopefully WS-Policies that we want to apply could use this transformation layer to apply its policy. This is AOP at the route level.
Exchange interception should also be possible in an easier way by registering an ExchangeListener: we need to provide some easy way to filter exchanges between endpoints (see SM-1064) that we could define on exchange listeners to filter source endpoint and destination endpoint. At the pojo level, I still think plain aop using spring has some values and should be supported (we don't have much to do afaik). What kind of use case do you have exactly ?
