If you're going to build a Raft demo, perhaps it should show strong consistency? Memcache supports compare-and-swap, so a distributed KV store speaking the memcache text protocol, and implementing a distributed CAS sounds like a great place to start! To my knowledge, a very simple distributed CAS doesn't exist, and there are plenty of memcache clients, so I also think this might maximize the odds people use hraftd in their production environments at some point.
