It sounds like you are purposely sharing KVs though. If I read your post wrong, I apologize and you can ignore me. But that is usually a pretty terrible idea. If you are actually buying the KVs yourself and willingly sharing and using the same ones, they will get eaten up very quickly. If you have the money to keep doing that, great. But if not, it would just be smarter to buy two KVs and each of you use a different one.
