Several years ago, before Linux embedded computers were available, and even before embedded processor "ethernet boards" were available, there was all kinds of chatter and efforts to "run CP/M on the Internet".

..the open question being, could a CP/M-class computer "handle" a
TCP/IP "stack"? The answer was "yes, it DID", as part of packet radio in the radio amateur community. Other micros like C64's were used. Later, packet radio "modems" were built with Z80-class technology; then 8035-class microcontrollers. You can still buy TNC's cheap at hamfests, I have a few lying around somewhere.
But around 2009 when I wrote the note, the "ethernet on a chip" products appeared and those were put to use. Now, it appears, one can just buy "Linux on a chip" and it does it all.
I'm a little sad that the vintage computer is mostly used as a terminal for "internet" access. But, it works both ways, so in principle one can use the $35 Linux bug as an Internet server and provide Web-to-console-port access to, well, whatever vintage computer has a serial port. I suppose with more effort, the Rasp Pi could more robustly operate a vintage computer, micro or mini. Then Bill Degnan's boast would become a reality: "email sent from my PDP-8".
Oh, that I'll live long enough....
