How to implement controller vibration / rumble?

It appears that these features aren't supported by Unity. If you have implemented it in a Unity-made game, how did you do it?

Searching for this topic yields some older threads referring to:

XInput for xbox 360; https://github.com/speps/XInputDotNet

Motionjoy for PS3; http://www.motioninjoy.com/download

These look like home-brewed solutions for exposing various console-specific controller features, including rumble. They're still being updated, so that's a good sign, but there doesn't seem to be much discussion here about them other than a few mentions of somebody getting them to work. So, this seems to be the M.O.: Use console-specific .dlls from 3rd parties, drop them in your builds and write a common interface within Unity. I'm wondering, is this still "the way" and are the above, the preferred packages (both for ease of use, and for indie-friendly licenses)?
