lintnode - a JSLint server for more expedient linting
I was setting up flymake-mode with JSLint, and thinking it was pretty great, but that rhino start-up cost is pretty big for a flymake application. If we just kept JSLint running, wouldn't that be a lot faster?
Then I caught a talk on the node.js server, and saw a way.
In my environment, this cuts jslint invocation time in half.
