Wow, nice to see you commenting here! btcd / btcwallet was an obvious choice since I wanted notification support. It's an impressive piece of work that you've created, and I really like the modular project design. At first I was worried that there was no documentation (yet) for btcwallet but the code is simple enough to understand even though I didn't know Go before.

btcctl is also really helpful. I only found out about it today though. Before that I've used curl and httpie and that was not very convenient.
