This is going to be a major pain for anyone with a cassette or freewheel block. It's dead easy to say you can just go single speed, but I will need to take a hacksaw to my cassette to achieve the correct gear (I run a 28t). Luckily I know how to do this, and probably have the parts. It could take a number of hours in any case! I expect I'm in the minority though, most will need to throw money at a bike shop and hope they are good at improvisation.
I don't think a 9 speed block presents the same hazard as a single, spare cog. Is that what caused the injury? I also don't think it will be possible to put a spare piece of chain on adjacent cogs, as this will foul on the drive chain.
