Congratulations SF: I an appreciate what goes into building systems such as this, that are the sum of it's parts, operating in real time, error control, proposed vs implemented solutions, and the ability to change course based on data. I just wonder to what degree of timing and efficiency this can all be done and to what degree of flexibility such systems can sustain and maintain integrity. All the data vs views, autonomy, capture, stream, while adding the ability for central and local resources to maintain control of their interest points and record histories of facts. Let me know if you want a perspective from someone who understands this from real time web systems perspective which is similar. There can be millions of users and authorities, building in real time autonomously or collaboratively, logging and subscribing to interests with views into latest or historical filtered sets, applying proposed and changed solutions, running tests, and sending out packages.
