Adding syphon support to impress to allow access to the rendered output from other applications

Presumably you mean an Impress slide show, and not the Impress UI (as
used to edit slide decks)?

As Impress slide shows typically are run full-screen, doesn't your
problem then (simply) become one of displaying the whole contents of
the screen (either the built-in one, or an external one if you have an
external one connected) on the dome? So if you find some way to just
display whatever is displayed on an external display onto the dome, it
will work for whatever application windows happen to be visible on the
screen at any moment. Or am I missing something?
