Feature request: integration w greenaddress’s permanent bitcoin address url

Green address bitcoin wallet assigns a permanent url that, when used, automatically generates unique addresses for every transaction. It would be nice to list that as my bitcoin address.

The issue names no files, tests, or entry points. Start by locating the existing bitcoin-address handling and determine how GreenAddress’s permanent URL would fit the client’s address model; done means the URL can be listed as the user’s bitcoin address and generates unique transaction addresses.
