I've seen snapped chains. It's always poor or incorrect fitment. Usually where someone hasn't peaned the link properly or peened it so tight that the chain can't flex properly.
It happens when you abuse it too (Like anything). Running badly worn sprockets can do it or having a rediculously tight/loose set up.
If you fit the right chain properly and replace your chain/sprockets when they need replacing then you won't ever have a chain snap.

I'm not disagreeing with either of you. There is definately no element of incorrect fitment or user error in this situation and I'm happy to put it down to bad luck. I can't think of anyway in which the user could aggrevate the failure of a sideplate. I get good use out of chains and sprockets but don't run them until they are worn out.
All I am trying to point out is that chains can be unreliable as can shafts but it is feasible to carry a complete replacement rear transmission system with a chain drive but this would be less practical with a shaft. With a shaft there is potentially a lot more to go wrong.
Don't find yourself sitting in the middle of a desert somewhere saying to yourself "chains snapping is not a valid argument here. They just don´t do that under normal circumstances" when you don't have a spare, because in my experience it can happen.
