Give credit where credit is due. Rogers/Fido invented zones and created Chatr around the concept. They are a way to artificially introduce roaming to their users for usage while still on their own network. What is one of the things people hate most about cell phones? Roaming while traveling. Rogers/Fido found a way to bring this to their users without having to leave the network.
