Going back to his email, here are the 'problems' he speculated exist:
1. <canvas> tag likely wont be patentable
2. consumers dont care about the security of videos. Most companies dont care about the security of their videos. So, these aren't problems that Clipstream solves because they aren't problems for those groups.
3. If the distributor wants to protect his content from being copied, then a plugin is required for him. So, is there a benefit for the distributor? Yes, but those are also available elsewhere (Netflix, Hulu, etc.) right? How is this 'security' feature is different? IOW is this an advantage or just a positive feature that already exists in the marketplace?
4. Is it really 'security' or 'privacy prevention'?
<<Here's another thing to note. They talk about security all over the place - because that sounds useful to the end user. What they mean is piracy prevention, which is useful for the distribution companies but doesn't mean anything to the average consumer. Again - very misleading, and downright shameful that they're trying to market it this way.>>
So, again, this comes down to the simple question: Who is expected to benefit from Clipstream in a way that is both useful to them and doesn't already exist?
