No, no experience on either side. I was just wondering. I think I'm working on a more basic level in my playing. I don't want anyone messing with that, and it's more ideas there. Teaching-wise, I wonder about issues like lag, keeping the same beat, the real sound, maybe something with being able to demonstrate something where weight is a factor.Longer term vs. short spot checks sounds interesting too. I could see it working or creating problems in both cases.
My primary reason for going on-line is that I ran into a superb teacher, and I can't regularly fly into another country. I'm not that rich.
