I'm not sure people are realising the potential of having a permanent server which didn't need you to be on it to exist. I feel like it should require a large forum based process to set up and would have options for mod rotors in a "permanent server" section in your user cp.
I'm not sure about the prices. How many people would be willing to spend that much on something like this. If there was a strong enough system to control people abusing this then such a high price might not be needed.
