But seriously, I'm not sure who this is for. It looks like there's quite a technical hurdle to setting it up - node.js and vagrant aren't easy to install for a novice user, and they aren't suitable for any shared hosting environment that I've come across.
I imagine (possibly incorrectly) that the market for simple point and click interfaces wouldn't necessarily overlap with that of people who are comfortable setting up complex hosting environments.
Now, as an online subscription model, I think it could be quite competitive. That's an entirely different route which definitely has a market.
