it's been done on snow, some people use it to get up the mountain, i saw it in a shitty warren miller flick a long time ago. looks really dumb, but if you don't have a chairlift and you're too fat to hike, i guess it's cool.
it would not work for kiteboarding. on water, not at all. the wind would have to be really fast and i doubt you could get the edge to get nearly as much air as kiteboarders. why just not kiteboard, kiteskiing wont be nearly as fun or cool looking.
you´re into huge airs but a big freakin kite that you can jump 50 feet high and travel 300feet with(hangtime above 10secs) isn´t something for you?
some kiters do lack style though, its said but true, it´s getting better though even if they do come up with some silly tricks(pass the board between yur legs etc).
Some guys here in ottawa have been doing it for 3 years, i've been kitesurfing for about a year and a half but just started doing it on snow this year and it's really fun! you go fast and can jump high so i don't see how anyone would not want to do it for fun.
