Replying to RC Snowmobile Idea?

After seeing many shots of people coasting their sleds down backcounty faces , a little idea flew into my head.  Why not implement an RC system so this could be done regularly and safely? 

Of course, this could be only used in certain areas, because losing sight of the sled would make things tricky.  However, in some cases, this could make things a little more fun when you take away the poor guy that has to take the snowmobile down.

Keep in mind that I am from the East Coast, and I have never skied BC or ridden a snowmobile, haha.
