First of all, this is brilliant. Like, truly.

Second, I don't understand it at all. I like to think that I am generally computer savvy, and I write from time to time, and I don't understand what the hell this is, nor how to use it.

I can tell there is a powerful tool here, but I don't know if a target demographic exists for this. Writers are, by and large, stupid, and computer people are, by and large, not concerned with literary aims. I can see this being a tool for editors, but as it exists currently it requires substantial technological knowledge on the part of the writer too, and the odds of both parties having this knowledge seem slim.

Despite this, I'll also challenge another of your assumptions; I think the right person would pay handsomely for this technology. Just because all the pieces are pre-existing and open source doesn't make the stitching together of them any less valuable.

I propose one of two approaches:

1) Develop a user-friendly interface which makes this accessible to a much wider segment of the population.

2) Specifically tailor and market this to a narrow niche that would appreciate it.

Have you read The 4-Hour Work Week? Tim Ferriss? Worth the read anyway, but this is your "muse," as he calls it. A potentially self-sustaining and automated cash flow which allows you to pursue other interests with less concern about how you are going to fund those pursuits.

Although I guess keeping it free and open source is a part of the whole mission for you. Whatever.

Anyway, I don't get it, but good job!
