Replying to Gear you would like to see on the mountain in the future

I have an engineering project at school where everyone in the class has to come up with a useful invention that hasn't been produced yet. I figured I would stick with something ski related. Does any one have a concept of something they would see useful on the mountain that hasn't been created yet?
I have over a year and a half to design/make a prototype for what ever it may be so any suggestions would be appreciated.

+k for good feedback
