Any chance this energy saving/hash increase could be built into the wallet miner? Seems to me that the whole concept behind the coin being easy for everyone to use and available to all is somewhat diluted by the requirement to use an external miner software (to get maximum hash rates) and will put a load of people off doing this.

Just a thought - but I think this could get more people on board in the long run - it is a great move - I like the idea of a "run in eco" mode and then a button that say - you know what - use all my computer resources cos I have solar!
