old_school I expect a similar response to this:

I am a teacher, and have been for many years. I know this software is in its early stages, but the functionality you showed in this video is available for free right now on numerous websites designed for teachers.
As for marking students work if you're marking it at the end of the lesson and not during the lesson (which is easy enough to do as you walk around the class) then how are you correcting misconceptions as they occur? It's too late to address problems after the lesson is over. I very rarely have to mark work at the end of the day due to the way I manage my classroom time. It's very different when it's comes to assessment time but that's only once every five weeks, and that only takes a couple of hours in front of the TV at best to finish marking, that is if I haven't finished it during my non-contact time, which is something all teachers get. You also have your GTMJs in front of you when marking the students work so it's easy to give the students the appropriate grade without spending hours of your time.
I plan my lessons based on the curriculum, so unless the questions you have designed meet the specific requirements for me (or any teacher) to get the desired lesson outcome then they are of no use to me other than as time fillers.
Finally, even if I did want to use your software, I am not allowed (as in completely unable to because of restrictions) to install or run any software which hasn't been purchased by the department of education.
EDIT
I also didn't lock this, and it wasn't locked when I started typing in my response.
