I think transporters could be used recreationally as an extreme sport: you could jump of a building or tall cliff, or even an airplane, and be beamed back just before you hit the ground... like a molecule scramblin' bungy cord or parachute
I'm not sure that would work unless you could also dampen the inertia during the transport. Otherwise, you'd just hit the transporter pad with all of the inertia you had built during your fall and splat to kingdom come.
