Okay, even though the first word that comes to mind is "disaster," it wasn't really that. I'm better with "tech" stuff when I can have things prepared ahead of time, and take my time. Using Dyknow in class requires me to keep a lot of stuff in my head to do on the spot, and I did not do so well my first time out, despite one-on-one tutoring with a colleague who uses the tool extensively.
My freshmen were helpful, offering suggestions about how to share a panel with them and so on. And it went better during the second class than in the first. That, I think, means that I am indeed teachable.
I don't see myself using it every day, but I do think that when I am more familiar with the software, it could be useful for some things.
