Question: Supporting dynamic changes to the topology once the runtime is started?

[vectronic]

The use case I am thinking of relates to demultiplexing media transport streams (MPEG Transport Streams).

In this scenario an MPEG TS multiplexed stream can contain multiple elementary video and audio streams (utilising various codecs) that can appear or disappear as the multiplexed stream progresses.

As an example, in case a new audio stream is discovered it would be desirable to add an output on the demultiplexer kernel and connect a new decoder kernel to this output. Similarly to remove kernels when an elementary stream disappears.
