From Cinda:

so, i want to be able to have people write a question on my tablet (in pen)
and populate the nodes of a decision tree with their questions.
on the next page.
my tablet or theirs, i guess, though i haven't thought that far.
so handwriting "Beer or Wine?" on one slide
would appear as a node in the tree.
any binary question.
i have an ice breaker where i ask people to pose questions that split the room in half.
and i want those questions to drive the lesson on dec trees.
also, i want people to be able to do a survey based on those questions.
so i can do data collection on the fly.
