There are two blueprints that I supposed to use for this purpose:

So my opinion:
This functionality should be orthogonal to what we configure in DSL.
The mechanism of listeners would is more generic and would your requirement as a special case.
At this point, I see that we may want to implement a generic transport-agnostic listener mechanism internally (not that hard task) and then implement required transport specific plugins to it.

Inviting everyone to discussion.
