This is somewhat of a first world problem for me, and I was wondering if there was a mod to suit my situation.

When it comes to storing my stuff, I am incredibly lazy (read: "I don't want this right now. Nearest chest, here you go").

Over time (6 months on my current run) Stuff becomes incredibly disorganized. I have about 75 chests scattered throughout my residence with zero organization scheme.

Other than the obvious of becoming better at organizing, is there a purely client side solution to my problem?

As far as existing solutions, I'm not sure, but I used to do some SMP developing, and this all should be possible with the current MC protocol sans server mods.

As you open a chest for the first time with this theoretical mod installed, it indexes everything in the chest and stores it locally, possibly giving the user the ability to not index this chest (Not their chest?).

When the user wants to search for something, it goes through everything it has indexed and highlights (Possibly a glow around the chest block visible above all other objects, like Zombe ore cheats. I can't think of a better way to deliver this information to the user. Maybe a Rei's Minimap point, but that depends on another mod, and I don't know how easy that is to integrate. I digress-)

This leaves the problem of chests that have been modified by other people. I can't think of a good solution to this without server mods. The simple and crappy solution would be to re-index a chest whenever a user opens it... albeit imperfect, it should be sufficient.

A more complex solution to this problem that stays in the constraints of not requiring server mods would be a few protocol injections. As a user walks by a chest, inject a head rotation packet, then a chest open packet, then a chest close packet, and a head rotation packet to reset to prior orientation. (I'm not certain if the head rotation packets are necessary. It's been a while) When the chest inventory data comes in, the software wouldn't render it to the screen, but instead index it and never show the user what it did. This makes initial indexing and re-indexing incredibly easy for the user.
