I don't think there's any possible way to get your BTC out of your SR account without having access to the account. I imagine SR just owns all of our bitcoin addresses basically, and when it receives a transfer it credits our accounts and starts passing around the BTC to filter it or whatever. In order to get BTC out of a bitcoin address, you need the private key for that address, and only DPR and his guys (or whoever wrote the software, you know what I mean) would know how to find that out and/or use it without being on the account page.
