USPS shipping flexability Request

@Aaron, hopefully you'll get this soon before my membership expires.
I had a thought about a possible solution for the USPS shipping section. On the checkout area for example
There is an arrow next to the USPS shipping method. Is it possible to add an option or options there that will allow a client to pick up in store and avoid shipping charges altogether?

Not sure how difficult that would be, but would really be nice.
