If you want to use insecure legacy protocols, then at least keep them close to the client, not up in the cloud, where anyone on the line can read your traffic.
This is exactly why I have a Pi zero installed into all my Amiga systems, to act as gateway/proxy between old legacy protocols (between Amiga and Pi, 15 cm ethernet or serial cable), and modern protocols (between the Pi and the big bad world).
This is interesting! What other modern chores do you off-load to a Pi Zero? USB? Through which Amiga port do you connect the PI?
If no one has championed it yet, I wonder if there could be a standard Pi Zero interface, similar in function to the old PC twin system, to add modern media and connectivity without burdening the Amiga OS.
