POST is not really JSONP.

You claim that your module can do a POST JSONP request, but this is not really true. In fact, in looking at the code, you handle POST using the old iframe technique (i.e. dynamically load the content into a hidden iframe); for GET requests, your code does use JSONP.  However, there is a key difference between JSONP and the iframe technique --- JSONP is asynchronous while the iframe technique is synchronous. If users of your code were not aware of this, they might code incorrectly (assuming that their POST requests using your library would be asynchronous). You should really disclose this fact more prominently.
