I'm using an earlier version of SublimeLinter. I'd love to create a plugin
that would work well for it at some point.

As Ilya mentioned, JSHint as an incremental parser, which makes it a bit
nicer in an editing context. That being said, however, as long as their
aren't any syntax errors when ESLint runs incrementally, it will give a
similar experience. Eclipse Orion is already using ESLint, so I'd be
willing to bet ESLint in its current form can be useful with an editor.

In the meantime, I'd just like to keep the .jshintrc file. :)
