This is great content. We're very interested to see people's ideas for
extensions, and happy to see development effort.
There are a few things I'd mention re: the diagram and notes:
* The VenueClient interacts with the NodeService, but not with
* Each Node runs one NodeService which communicates with the
ServiceManager running on each of the other machines in the node
(those Other machines don't run NodeServices)
* The NodeService communicates directly with Services in the Node
* The description for ServiceManager seems to describe the
NodeManagement user interface; a ServiceManager is software that
runs on each machine in a node for controlling execution of Services
* The description for Services says that the VideoProducer runs
multiple copies of vic, but it's actually one vic per
VideoProducer. So, a video machine with four capture cards would
run four VideoProducerServices (and, therefore, four copies of vic).
I hope this helps clarify some issues. If you have any questions,
