Looks nice, but the Aloha licensing basically requires you to buy a license if you're going to use it commercially, whereas this one uses the very simple and open MIT license.
Furthermore, I've been trying to get them to sell me a commercial license for months. Someone sometimes emails me back, but they have yet to give me a way to give them money.
It's licensed under AGPLv3. I prefer MIT as well, but surely you don't need to buy a licence to use this?
