Web4 will be fought with telnet to port 80

It's certainly possible to serve an entire copy of Wikipedia and Gutenberg off a 15 year old PC.
However my experiments at 300 baud on Wireless 20 years ago suggested that at that speed only NTTP, POP3 & SMTP with plain text worked sanely. The overhead for HTML, never mind HTTP, is too high. SFTP/SSH depends only what it is. A pigeon with a mircoSD card can be better. Or sneaker-net with microSd, USB sticks / USB HDD instead of 1980s floppies for large file transfer.
