Teaching/buddy mode to allow others to try out Carv more easily than current buddy pass system

Have option for someone to borrow Carv to try out for a couple of runs (without having run permanently recorded as part of your own skiing).

Useful if you are teaching a class and want to take turns having each student try out Carv for a run. Then have an option to email the result/metrics (just for that run) to someone along with referral link so they have option to buy their own Carv unit.

I understand there is a buddy pass system already, but we can't expect students or friends who aren't all that interested in Carv to go through the trouble of setting all that up. It's got to be as easy as clipping the Carv unit to their boots to "try it out" and once they see the results and how much data it can collect, then they will be hooked.
