Ship rush integration

I noticed you only have integration for USPS and I tested this and it's not the great. I also use Ship Rush with our inventory and warehouse management software (stoneedge) and it really works great. You can see more about Ship Rush for developers here http://developer.shiprush.com/ . If you integrate ship rush it will allow us to ship with any carrier we choose to get a license for through ship rush. This seems like it would be easier and more efficient than having to integrate with each shipping carrier directly.
