A linear distribution curve that matches work/watt input. This modestly levels the playing field, although it simply allows existing capital to match the input/output. Satoshi style curves are both capital dependent and skewed disproportionately to the first to arrive within the tiny timeframe.

Anti-sybil attacks would be immensely beneficial. Encouragement of honest economic activity. Scaling of bandwidth and fees.

The ideal solution is a PoW that is computationally useful and desirable, BOINC, folding@home. Ethereum almost does this, but PoW algos as they exist now are anti-scale by design, where increasing computational power does not improve the network at all.

The foreseeable longevity of PoW is ungodly waste, when a world wide distributed computing network has potential far far beyond brute force hash puzzles.
