I looked around and there is no other cross-platform bsd-like socket
except libuv (https://libuv.org/).

If we have cross platform bindings for that it will allow us to create
a couple portable implementations for on-going pre-srfi like http, p2p
and cell-terminal. Possibly others like database drivers? Even if it
is a lot of work to create database drivers starting at the wire
protocol.

I think I will start a specification for libuv low level but schemey bindings.
