And I can tell you right now, a lot of newcomers won't know the whole bind thing. I doubt I'll even bother binding keys for this server.
As for jailbreak, the point of it is to either obey and play mini-game type things until your all killed off, or rebel and kill the cops. If you want mini-games, turn the server into a mini-game server. They have those, don't they? Ceiling Cat plays in one all the time.
If you did make a jailbreak server, you would have to create a completely new set of rules for it. (Where you can get stabbed if both you and the inmates are in a certain area, what you can and cannot do, what you can be banned or kicked for, and so much mroe) I doubt you want to put time into something like that.
At least if WCS doesn't work out, and you consider making two separate ZM servers, each dedicated to a type of play, you would have everything there already. And old regulars would start playing more.
