Started to respond to Doug yesterday then my internet went down... all day! To answer Doug's questions:
Our club started receiving IRD's almost 3 years ago. We use Zoom for all of them. They are very interactive (ie: clip of
Jim Echner IRD to Central Arkansas Woodturners) . Up until earlier this year they were generally just called Remote Demonstrations. But as the community of demonstrators grew I suggested that we add the word "Interactive" which is the key component differentiating them with youtube videos. It stuck and earlier this year and has been adopted by all. It was Trent Bosch who pioneered the idea just a few months ago of offering IRD's to anyone who paid a $10 fee. As opposed to one broadcast to a single WT club. Trent calls his Personal IRD's but I think that is misleading in that anyone can sign up, and 100 people it's anything but personal. Hence, I have suggested to the community that we call these Public IRD's.
perhaps single point ones to a club could be called "Club IRD's. but I don't think it's nessesary. Although there is a critical difference between the IRD's broadcast to a club in the past and the newer Public IRD's. In the past the Club IRD the demonstrator one had a single internet connection, the one to the club's meeting place. Simple. But with Public IRD's a demonstrator could have 100 people, all with a separate connection. (Cindy had 127 on her's last week.) This adds complication. A demonstrator needs a co-host to monitor the questions that come up through the chat.
Hope that helps.
