TCP multiplexing protocol

A high-level approach to multiplexing multiple TCP connections over a single socket. Probably ignores a lot of queueing theory.

Background

The CC3000 WiFi chip may be especially unreliable if more than one socket is in use. So the idea is to maintain a single connection with a proxy server, which will handle the actual simultaneous outbound connections on a client's behalf. (Inbound connections are lower implementation priority.)

Terminology

This is what Craft does:

function loadFramework(pluginRoot) {
  if (NSClassFromString('PanelsManager') == null) {
    var mocha = [Mocha sharedRuntime];
    return [mocha loadFrameworkWithName:'Panels' inDirectory:pluginRoot];
  } else {
    return true;
 }
