I was hoping someone could make a plugin that when a sign gets a redstone signal, it will execute a certain customizable command. Ex. If you want it always to be day, you just have it on a timer, then the sign's command is "/time day". Do you think this is possible? If it already exists where can I get it? I saw an older version but it did not work...
Shameless self promotion alert: my ScrollingMenuSign plugin can pretty much do this. http://dev.bukkit.org/server-mods/scrollingmenusign - if you go through the QuickStart Guide, the part on redstone views might be helpful.
