Farming question - when lots of people only have PC on in evening

I’m thinking about all the aggregate bandwidth of cell-phones and tablets using high speed NAND that are at home in their charging cradle at night. I wonder if some kind of lesser reward for cache would help. I get the impression that paying too many GETS for super popular cached data and reward imbalances were seen as a security/stability issue. Even so, serving as a cache store does provide a resource, so it seems logical to want to be rewarded for that. @neo, I saw that you were part of some of the cache conversations, can you provide more clarity on the matter?
