I thought of mostly the same things (redis/some other database), maybe also IoT? This, in combination with the ultra low power wifi post that recently went up (https://news.ycombinator.com/item?id=13135607 https://news.ycombinator.com/item?id=13135607) seem like they would go together. I think cloud vendors would definitely charge a pretty high premium for this, since it requires more than zero work on their part. Also, aren't most simply-distributed databases constrained to single node performance (for writes, assuming one master)? I feel like you could work in fast reads to this scheme too, if you required replicas to have a complete log in order to respond to a read, since it's all or nothing. The possibility of a slightly (1 op) stale read is possible though.
