Tcl?

It's socket support was good enough for me to have written variety of
network clients in it (POP3, LPD, NNTP), and it is fairly easy to extend
further as needed. Shared library above could be built in statically for
some gain in size and start-up speed, or left as-is if you are running
your own things with Tcl interpreter built-in.
