Michael, this is a slippery slope. I would have loved to attend the summit this year, but other commitments kept me away. The extra two days of content were restricted by an NDA, which I signed, so should I be allowed to see the videos even though I was not able to attend in person?
Regarding the other content, I feel it is down to the presenters on an individual basis to opt-in to allow their videos to be shown on youtube. I am pretty sure NI has no claim the the IP in those videos, and would be foolish to prevent non-restricted content from being made public. Although only CLAs were invited to the summit, but I do not really think it is fair to restrict that content from non CLAs who want to take the time (probably their own personal time) to watch it and perhaps learn something. The world needs more people skilled in LabVIEW in my opinion. The CLA summit is not quite as closed as you think to non-CLAs, there is actually a precedent already set in that the first CLA summit in Europe, held at NI UK HQ in Newbury was open to CLD as well.
