Bukkit

• v1.0 beta: completely rewritten the code!
  • previously, the indexing code loaded all the chunks in the world, one after the other, to see if they contain some inventory holders. This was really slow. Instead, in this version the plugin reads the region files directly;
  • put the indexing code in a separate thread: no lag any more!;
  • added a command to stop indexing (/itemfinder cancel-indexing);
  • if you have ProtocolLib installed, you can teleport to the results of the item search by simply clicking on them while in chat!;
  • fixed some mistakes in the permissions;
  • now needs PowerNBT as dependendy and ProtocolLib as soft dependency;
  • added an update checker!.
• v1.1 alpha:
  • disabled the player to search for an item before inventory holders have been indexed;
  • made the plugin predict how long it would take to index all inventory holders;
  • other small bug fixes;
• v1.0.1 alpha: made the plugin compatible for Java 6;
• v1.0 alpha: created the plugin (duh).

For some reason, which I can't seem to figure out, sometimes inventory holders are indexed twice. This means, when you search for an item, you will probably see in the results more than one time some locations. Also, for the same reason, the config is twice as big as it should be.
