Last time I suggested this I went about it all wrong. Instead of forcing everyone to accept mobs spawning in town, why not allow us to turn mob spawning on in our res's with it off by default? Here's a question for JustinGuy or someone who might know. Would allowing mob spawning in your res turn off that "safe zone" people enter when they go into the wild? If so then when a creeper explodes wouldn't not explode if mob spawning's off or does it have to do with keeping TNT false? To the people who don't want mobs in town, this won't effect you in any way except allow the occasional mob to come in and push you around at night which would only be a minor annoyance a wooden sword cloud fix in a jiffy with no damage unless mob spawning is set to true in your res assuming it works the way I think it does. This could allow people to have that true Minecraft survival feel in town, allow people to make dungeons, collect mob related items like gunpowder in your own home, allow both snow and iron golems to finally spawn in town making iron more renewable. Again people won't be able to grief you if you keep the tnt flag and mob flag false again assuming it works the way I think it does, otherwise I guess mobs in town won't happen.
