Can you give a quick overview of what changes might be required for this?

Not having looked into the APIs, I would assume that having different 
workspaces on different displays would fit nicely with the hooks already 
present in Genode (as opposed to workspaces spanning multiple displays). 
  To my mind, this would handle the vast majority of use cases for most 
users.  Am I off-base here?
