There's a number of ways to tweak the algorithm, e.g. by generating multiple hashes per endpoint and then distributing them around a unit circle. I've seen this used to consistently allocate customers to a particular set of servers, not just ensure you are hitting the right cache. It doesn't fully solve the subscription issue where multiple people are in multiple channels, but it could probably be used as a building block there.
