This is an interesting point, and one I guess that isn't really an issue in places I've worked. I can see that it would make sense to ensure that this runs in the "correct" (often a clean) container.

The exact way you would specify that you want to use a particular "installed" container is to enable the container in your POM, by adding a dependency to the connector, and then specifying the path to the container in the connectors properties. This seems pretty explicit to me - but is it enough?

I still say that as long as the behavior is easily tuned (enabled, disabled, proper instance location) and sufficiently documented, we should offer the flexibility for the remote container to be started automatically.
