I think you can build that (out of strings and duct tape, kind of) by screencasting onto a canvas, and then re-screencasting a part of that canvas. I'm sure there's missing pieces in that pipeline, though - I don't think we have defined a way to create a MediaStreamTrack from a canvas yet. It takes more than a zoom constraint to do it, however; at minimum you need 2 coordinate pairs (for a rectangular viewport).
