Architecture: WiFi support for WiFi enabled boards ...

Ok, so you'll need to do:

include "jswrap_modules.h" // for jswrap_require

/*JSON{
    "type": "library",
    "class" : "foo"
}*/

static JsVar *getFooModule() {
  JsVar *moduleName = jsvNewFromString("foo");
  JsVar *m = jswrap_require(moduleName);
  jsvUnLock(moduleName);
  return m;
}

/*JSON{
    "type" : "staticmethod",
    "class" : "foo",
    "name" : "bar",
    "generate" : "jswrap_foo_bar"
}*/
void jswrap_foo_bar() {
  JsVar *module = getFooModule();
  if (!module) return; // out of memory?
  jsiQueueObjectCallbacks(module, "#onbob", NULL, 0);
  jsvUnLock(module);
}

and then this works:

>require("foo").on("bob",function() { print('Hello'); });
=undefined
>require("foo").bar()  
=undefined
Hello

It's a bit nasty. With the prototype chain branch I'm hoping to tidy it up so you'll be able to do:

/*JSON{
    "type" : "method", // <----- changed
    "class" : "foo",
    "name" : "bar",
    "generate" : "jswrap_foo_bar"
}*/
void jswrap_foo_bar(JsVar *module) {
  jsiQueueObjectCallbacks(module, "#onbob", NULL, 0);
}

But right now I think the safest method is above, and should be easy enough to tweak later on.
