Not such an arrangement in my cong. But I hear about something like this. If anybody ask, I tell them I like to look it for my own, it's better to follow and I can stop in between and think about it. I only read the summary on the websites, so I'm mostly up to date.
But seeing Lett perform the show in the hall or with a group of dubs, it's more then I can take.
I think, nearly all congs got a beamer or videoscreens, so we will have more and more broadcast-style meetings.
