We run offa Bukkit.
Creeper Mod so that creeps leave the blocks alone.
Planned Plugins for Saturday but Really Sunday Update:
Iconomy - Storefronts, Currency (Peeniis is our choice for money name. )
Towny - We are gonna have two towns, which players are free to join. In the towns they are protected from damage from other players, no mobs will spawn in the town save peaceful ones, and their blocks cannot be damaged by anyone save for themselves, the mayor (town admin), and anyone they allow. There will be taxes on the plots, but that money will goto town projects, expansion, and other crap the town wants to spend it on.
LWC, we have no donators, so you all will have the option to use it.
PVP: There will be war events between our two towns eventually. As far as day to day PVP, everyone is protected in towns, but outside in the frontier, all is far game. LWC will prevent theft, so if you are out and about, make sure you deposit stuff. We may implement a bounty system, where towns can mark a person for a money bonus for kills. I dunno. Maybe.
Future planned updates:
Industrial Craft
Plasticraft
Chocolate Mod
Bee Keeper, if it doesn't bog down the memory usage like we think it will.
Coral Mod, provided they fix the memory usage on it's generators.
Mo' Creatures, when it gets moved from 1.4 to 1.5
Mo' Foodz, when it gets moved from Single Player to SMP
Mo' Treez for the same reason
