Quantum Gateway Inline Frames - Version 2

What can I do with this module?
* Version 2 does everything Version 1 does.
* Posts all data except the method and authenticated session. See IFrame source v2 example below.
Name, Address and other billing or shipping information are sent in the POST instead of GET.
POST data can not be seen by a customer.
GET data can be. GET data is everything like in your browser address bar.

POST is more secure than GET because it is harder to manipulate what is being sent. In version 1, the first name (FNAME), could be more easily manipulated. Where as the POST value is much more difficult.
