For those outside Australia, you can pay most bills at the post office (Australia Post) or online via the post office's PostBillPay service. Basically, AusPost act as a middleman between the biller and the customer. But AusPost only accept Australian Dollar payments.<p>So from my reading of it, Ryan's project takes a bitcoin payment from the customer, converts it into AUD, then connects to PostBillPay and pays the bill, then send the customer the receipt from PostBillPay.<p>Bill payments 1.0:
Customer -> Biller<p>Bill payments 2.0:
Customer -> PostBillPay -> Biller<p>Bill payments 3.0:
Customer -> BitBillPay -> PostBillPay -> Biller<p>It's a great idea .. but I imagine if it takes off, AusPost will implement pay-by-bitcoin in their own service.
