Absolutely. This is a key address-non-reuse case we really need to solve. Miner payouts, BitPay salary payouts, etc. all use a statically provided, manually changed address. Rotating through multiple outputs is a stopgap -- but IMO a useful one. HD wallets will solve this in a better way, but existing randkey systems will be around for a long time. -- Jeff Garzik Bitcoin core developer and open source evangelist BitPay, Inc. https://bitpay.com/
