I just got done talking with my Father via skype and camtwist 1000ish miles away in his RV. I needed help with a plumbing problem in my house. I took a picture of the plumming problem, then used the telestrator to draw ontop of the picture. I didn't connect my camcorder, so he didn't get to see me, but he could see the picture, I could see him, and we could both hear each other. It worked very well! The only thing that would have been nice to have is a pointer of some sort, instead of drawing and erasing lines all the time. Does such an effect already exist?
Thanks for listening, and the great application!
