Hi Steve,

before attempting to hack BitcoinJ to use NIO you might want to take a look
at BitDroid (https://github.com/cdecker/BitDroid-Network), which is my
attempt to build an easily extensible network client (no crypto stuff so
far) on top of NIO and a simple publish-subscribe architecture. I build a
crawler like yours with just a single class that subscribes to events
published and closes and opens connections to crawl.

HTH,
Christian
