This diverges from the topic but seems like a good idea to me in general, not so much as replacement for jgarzik's proposal. Something like `getutxos` or this proposal could be implemented as an external application or script, instead of having to integrate everything into bitcoind. Bitcoind would need a local interprocess message bus for that, and would need to act as router for messages from/to the P2P network. ZeroMQ seems like a good choice for that. That's not completely crazy as there are already plans to add zeromq as an optional dependency for notifications [1]. [1] github.com/bitcoin/bitcoin/pull/4594 Wladimir
