Just reviewing the comments made on this thread again.
As always, whenever there is change, innovation or evolution there will be those who see the bigger picture and grab the opportunities presented. There will also be those who do not, will not, accept any change to their existing order of things. Each has the right to pursue their views.
GBF -Thanks for letting me know what my agenda is-it is good to know, but you're wrong.
APH - Handing around can be done but we don't have the facility to do so for this particular event. Check out some of the USA clubs that have done this and see how they have solved the problem, particularly the Trent Bosch demos, for example. I think this aspect is also something that the UK turners who are setting up studios for remote live demos need to consider.
As for Zoom in on request and good close-ups, well with a 3 camera set up this is easy and works well - at least it did when we asked Lyle to do this for us on our trial run. His overhead camera, which is only a small Logitech one, gives a superb resolution picture.
I suppose this is where live remote demos beat YouTube - because you have live real time interaction with the demonstrator just as you would have if the demonstrator was in your club venue, except in this instance, the demonstrator is 3000 miles away. It's probably easier to catch the demonstrators attention if you're talking directly to him over a video/audio link, rather than to have to shout out from the crowd in a demo, and may not be heard.
The other issue to consider is that for some clubs, remote live demos may be the only affordable way to get demonstrators to their club - I believe this comment was made by a club events organiser on another thread on this topic.
In case you have missed it, this is the link to Alan Zenreich's rotation on this topic -it shows what can be done with the new technology - even if it is just your smartphone.
