It definitely could have some interesting results, I'm imagining those hosted mining companies that let you buy hash power, only with this you could have a market (rather than a few big players) that has much less friction.

I find the idea attractive, that mining in the future could be mostly or all at home mining, even when it isn't profitable; one of the reasons I've heard for this is eventually all governments will be faced with the incentive to control or ban mining, and at home mining can blend in with normal power usage. I find this to be unrealistic with today's options, because even a single 3kw miner will be very obvious to anyone paying attention; but if we could see 1kw miners take off then it would be difficult to detect, and a system like this would be a great fit for that high fee future.
