I think I would too. I like the idea. Not sure about calling it Hemingway, because I am a huge fan of the writer, but I would like to have something like this available for Sublime.

It might have to deal with markdown.

Another vote that I would like this within Sublime (although I'm not sure how that would work), and would really like for the tool to be able to interpret Markdown. Right now it gets confused by the markup for hyperlinks.

Looks like a great tool for me to take rambling blog drafts and trip them down while editing/refining.

Does lots of written work in restructed text and would buy as well (a sublime text addon, for example)!

It would be great if there was some way to write Sublime / Vim / whatever plugins that use this.

Not if it uploads my texts to some 3rdparty webservice, though

Ya that's one thing I would like to avoid also.
