Do you have some examples of network scripts written in Gawk? Particularly something that you'd prefer to write in Gawk rather than in a more "general-purpose" language. Would be interesting to see.

(If you want it to fully function you'll need bits of code starting here -- https://www.gnu.org/software/gawk/manual/gawkinet/gawkinet.h...)
The general procedure for using a Gawk socket is just building a string of the form `/inet/tcp/0/example.com/80` (example.com, port 80) and redirecting to/from it as a coprocess with `|&`.
