Potential add-on board?

[kirk_m]

I give all my Amiga systems a pi (zero), primarily to act as network bridge, giving them wifi (with modern capabilities) and hence avoid the need for cables all over. Bonuses are that the pi also can share filesystems and give Amiga access to USB storage (imagine if someone wrote USB-over-IP driver for Poseidon), playback of music files can be offloaded to the pi, it can act as web proxy and bypass the hurdle of resource hungry modern SSL/TLS handling, giving rsh/rlogin/telnet access solely to the Amiga, it's the "jump host" for ssh out to the world... it also acts as name server, ntp server and whatever else I find useful.

I am curious if it would be possible to network Amiga with Pi directly over parallel port, using the GPIO pins in the Pi. It is of course possible via Plipbox

I'd love to see documentation of how you did this.  It sounds awesome.
