Even if the miners vote against the reward, the reward is just deferred. If miners ever vote for the reward in the future, the deferred rewards will be paid out. So it is pretty much a 1% premine, with a lock released slowly (and at an uncertain rate). The only way to get rid of the reward entirely is to hard fork.

Boolberry has no trailing reward at all, it just goes down exponential to zero eventually like Bitcoin.

On the matter of reducing the percentage every year that seems so close to a fixed tail reward amount that it doesn't seem worth pursuing as a distinct option. As I stated on reddit I prefer a fixed reward as it has self-stabilzing properties. In erok's case of burning, the fixed reward becomes a higher percentage. regrowing the money supply more quickly. If none is burned or lost, then the percentage shrinks. This tends toward a constant money supply that is a function of the average long term burn/loss rate.

But I think an small exponential percentage is not bad either. At 1% inflation, at most (assuming no burn/loss) 50% of the share of wealth of a holder who does nothing else to add value to the economy is redistributed over 70 years (sort of a lifetime, though this might be longer in the future). Even in that case the amount of wealth may still increase if the value of the total money supply grows >1%/year. I have no problem with that.
