@lanodan @benis @wolf480pl Without revealing too many details, they already are.

You might not have seen my crap draw.io example but printers are spread across multiple networks (there's also multiple guest networks).

This solution needs to scale to work across a theoretically infinite number of guest networks, with a theoretically infinite number of printers across an infinite number of separate networks.

Some guests might also use their own internet connection rather than our standard guest network.

Hence why a proper push/pull model to/from the internet is pretty hard to get away from.
