I believe I have seen rapelling gear on some price list sometime, might have been the Equipment Guide or 2ed Aurora's... can't remember.
The point being, this kind of gear does not really have to be that complex, like the gear we use today (yeah I'm a climber/instructor too). A harness can be made from simple rope, the old guys back in the day used to climb and rappel with a hemprope tied around their waist and we are talking fantasy now. Why restrict creativity, it should be nurtured and valued in players, especially if it creates heroic moments and memorable gaming sessions.
