Neil, this is all correct as I understand it. Only changes are sent, but if you only care about the changes in 1 corner, you will get it all anyway.
The right way to solve this is to just use 4 different displays. I.e. You have 4 separate desktops showing whatever you care about, and then the 4 clients you are showing this stuff to, will have 4 unique connections, 1 to each of the 4 separate desktop connections in Guacamole. You are trying to break how guacamole was designed to work, when the "guac" solution is right in front of you, have 4 distinct connections, to 4 distinct desktops, 1 per "quadrant" as you are saying. This way you aren't trying to break how guac works, for no good reason. Just have 1 app on 1 desktop display whatever is on quadrant 1, which would be 1 desktop connection in guac and so on. IF you have some requirement, where you have some physical display that needs to see all 4 on the same physical screen, that too is easily accomplished with 4 browser windows, 1 per guac connection. It will be basically just as efficient as what you are describing, but with no actual code or work on your part. You don't need to invent anything new here, no new code or feature is required.
