I don't know if you're interested in making the "telnet" experience better, but something I've seen used elsewhere is a well-known/advertised SSH login. At the very least you can enable compression on SSH connections. Compression level 1 is nearly free in terms of cpu. For instance, try `ssh joshua@crawl.akrasiac.org`, and the password is again `joshua`. If you're allowing anybody on the internet to SSH in, you could also use mosh (mosh.org) to make it feel even faster.
