#include <net.h>

// this outgoing "telnet" socket thing implements both '/set mudlink'
// for users as MUD chatrooms such as @nemesis. would be cool if it
// actually was capable of handling telnet protocol, but the mud in
// question isn't, either.
//
// for a tighter integration between psyced and MUD it would also be
// cool to either have a native PSYC side channel, or to embed crypto-
// graphically signed PSYC packets (using a shared secret hash) into
// this stream.

// message queueing and automatic reconnect mgmt
