Kite board on a yak?

Has anyone done it or seen it done. Could one use a kite board if it were tethered to the yak and controlled by the traditional pull cords. I have never kite boarded or been close enough to see how there rigged. On a windy day I bet you could get moving.

I have tried a regular kite from mine.  I picked a day with erratic winds though, so little success...  When it's up, it does act as a nice downwind sail.  I have had better luck with the V-type sail I built, although it has its share of problems too (poor design, what can I say...).
