I'd prefer to have one based on nc and sh as it's more portable (think busybox systems).

Also, check this for gopher:

Now you can browse HN, play IF, read news, and so on over Gopher with just Busybox (sh, grep, tail and netcat requiredin the busybox build) and an internet connection:

gopher://hngopher.com

gopher://mozz.us

Altough with just less, echo and nc:

     echo / | nc mozz.us 70 | less

     echo /long/selector/to/a/text/file.txt | ncmozz.us 70 | less

Crazy but it could work on heavily tiny restricted devices such as a RetroBSD with nc, echo and less in a tiny microcontroller.
