A proposition to get the application out of the way most of the time would be
to:

a) make the event sticky. This will let playbing element to dispatch their
newly created context and expect it to be distributed whenever element are
linked.

b) Add handler for the have-context message and redispatch that context to any
existing element. Element htat already have a type of context set, would simply
ignore the newly dispatched context. This is to enable having multiple context
within a single pipeline. As this is a special case, it will require special
action by the application.

This is just the big lines, I'll be digging into the code soon to fine more
details that might be required to get this running.
