One plugin that I was looking for but couldn't find would be something that recreates the functionality of 303's torch arrow in multiplayer. I know that having it as a separate item isn't possible on multiplayer (yet), but it'd be great if someone could code a plugin where you type in /torcharrow and every time you fire an arrow, it subtracts the arrow AND a torch from your inventory, then places the torch wherever the arrow hit. If you're not familiar with 303's arrows, video: http://www.youtube.com/watch?v=4sjegyxHEhA&feature=player_detailpage#t=62s
I second this! The only thing I found to have functionality similar to this would be this: http://forums.bukkit.org/threads/mech-fun-torchmissile-v0-2-shoot-light-into-the-darkness-677.13051/ And /ta would be the command I would think. Cookies and shrooms to all those who make this.
This could also be rolled in with a feature to use /firearrow and light the target if its flammable (with an option to limit that to flammable mobs, since most admins don't allow unrestricted fire )
