i think it'd be much better if the block solver got all the TX fees instead of however the reward system works now (and, no, this isn't favoring someone that's 60ghash, because like the share difficulty, in the long run it would all even out).
I'd like to see the reward system change as well. The current one doesn't give much incentive. I like your idea, all the TX fees go to the solver + his portion of the block.
