For some reason, I've been thinking about the Bluzone a lot recently. So I had a dream on it.
Anyway, I was also thinking about some sort of **Bluzone system. I don't it has been attempted before. Goes something like this:
The server is a dedicated, passworded server.
When an admin of the server comes in, he/she will enter the password and proceed to join the empty server. He/she can do one of two things:
1. Keep the server locked, if he/she just wants to work on the darn thing (though unlikely because it's quite hard to build on Slate Dark);
2. Remove the password for public playing.
If the admin chooses to unlock the server, he will then set the player limit to something he can handle. Something like 3 or 4 players for every admin on the server.
Then they play...
...and play...
...and play...
...and play...
...until the last admin needs to leave. He'll have to forcibly stop the RP, lock the server, and leave.
(Think of it as a regular building: A staff member comes along, unlocks it, people go in and out and do stuff in it, until the last staff member has to leave. Shooes all people out, locks the door, and proceeds to abandon the building until the cycle starts again)
