Yeah, I think thats a very reasonable viewpoint to take. To me there was a lot more depth in what you just said that the OP.
What I will say though is that to me when you 'envison.. in a somewhat ugly way' its basically a guess that they won't find a nice way to solve the UI difficulties of things that weren't in the video. You might be proved right, but to really know (rather than guess) this, you need to spend probably some days thinking about and prototyping it, which assumedly they will do (and we have not).
I think they should be encouraged to do so, and my main problem with the OP was its basically discouraging tone of 'its never going to work because you haven't shown me a perfect final version that covers all bases'.
"you need to spend probably some days thinking about and prototyping it"
I would _guess_ that "thinking about it and researching it" will be time better spent. Inventing the wheel often is a lot of fun, but it also can be a waste of time. I do not know the literature, but it would not really surprise me to learn that there is some cheap knowledge to mine from it.
