What I suggest does not require the Discovery modification to be altered, it is much simpler. The change of starting location can be done server-side after each maintenence, so it would practically change from day to day. I don't know how to implement that precisely, but it shouldn't be too hard. Besides I can't know what kinds of server-side software is being used. Some administrators might know. One-way jumphole system would require a mod change. And it would look ugly.
