Is there a tool that already does this? If not, what would be the best architecture for building an event driven chain of ttys? What would be the biggest difficulty?

The part of the description you repeat is a bit of nonsense. Actually most of that issue is.

I interpret it as asking for emulation of a taller window via two or more columns.

Your response here is a bit of a nonsense, actually most of your response is. I interpret you need help, otherwise yes that's another way of rephrasing the problem.
