Hi Ruben, three things:
a) It is great to see that another one of the main project partners is well-headed towards a production system! b) The approach that you are taking by using the capture agents as workers is interesting! As long as you can afford putting more expensive hardware into the lecture halls, the processing capacity grows with the potential number of lectures that you can store, which is a good thing. As downsides, I see potential security problems (the capture agents, which people theoretically have physical access to, now need to be able to access the backend services and data) as well as the potential to influence recording quality if an encoding job takes longer than expected. But maybe you have taken measures to prevent this which you didn't share in your e-mail. c) You should really send this e-mail to matterhorn-users as well, since many adopters will be interested to look at what you are doing!
