It's kind of an interesting thing to try and think through. I think emily37's post above brings up one of the more motivating usecases that's going to be much more forgiving when it comes to practicality, which is allowing someone who doesn't want to reveal how they do math on the data and someone else who doesn't want to reveal the data get together and make answers. As for POS systems, I feel like public key is going to be far more applicable than homomorphic is for the usecases that make sense there. But I definitely could be missing something. :)
