There's also some resources that are by no means the only, or even ideal, way to implement sharing strategies in alternative currencies and economies, but they can give you a sense of how this is being done in a decentralized fashion around the world:
Thank you for sharing. I really like that concept. If you honestly have "private areas" it can work really well for all involved. My wife and I had her biological mom living with us for a few months in three different houses and it worked alright in my opinion. Now according to them I'm sure they have a totally different opinion. Now my wife and I live in a 1 bedroom house so we don't have room for extra people anymore. It was hard for us to do as a couple with no kids living with another adult in the house. If any of the parties aren't mature enough to act like adults among all the other adults it can really be hell. That's just from my own experience.
