These signs could be a thing of the past if CLOO, a new phone app, takes off. On first reading you wonder if it might be a spoof but eventually the world could become your toilet if Hilary Young and Deanna McDonald of CLOO get the investment they are looking for. Social networking is taken to new levels as people register to allow others in their city to use their bathroom. People can avoid the MacDonalds or Starbuck toilets for the price of a latte which is paid to the owner of the bathroom. Through your existing social networks you'll be able to check if the hosts in your area are friends, friends of friends or just complete strangers. Post-toilet-visit CLOO is inviting both hosts and guests to review and rate each other's performance. Perhaps this idea could spread to all the facilities you have to offer in your home.

Rosie Grey from Village Voice described it as "The future start up that may save you having to pee your pants'.
