[mongodb-native](http://mongodb.github.io/node-mongodb-native/) has full ES6 Promises support since [2.0.36 2015-07-07](https://github.com/mongodb/node-mongodb-native/blob/2.1/HISTORY.md#2036-2015-07-07). Shouldn't `mongosking` support Promises too? To do so you'll have to rewrite [SkinClass._bindMethod](https://github.com/kissjs/node-mongoskin/blob/master/lib/utils.js#L77) wrapper, If you'll approve my proposal, I may try to implement it myself and send you a PR.
