Existing Slots. New and old ideas.

This post is about existing slots and idea about placing (old/new) items into them.

I.Action Slot
1)old (existing) items:
a) hats -- throw up, if you win (random exchange with others, who threw the hat too?);
b) weapon -- if somebody wins you, he takes yours, though he must placed his weapon too;
c) scrap metal(lvl 1) -- drop the ammo-box (only engy?);
d) alien parasite* -- throw it onto the enemy (the same effect as in Alien Swarm); if the enemy dies, then the parasite returns, else - it dies;

2)new...

II.Misc-Slot
1)old (existing) items:
a) hats -- mini-version of the hat is input into the special frame [{icon of the hAt}]
b) weapon - mini-version of the weapon [{icon of the weapon}] warns your enemy that you have a skill with this weapon;
2)new...

Project 'Itemcrossing'

If you know about the existing Bookcrossing, it's clearer to see analogy.
The idea is: leave[drop?] your item anywhere on the map, so it starts it's journey through multiple backpacks.
It could have special quality (also read my post with ideas of new kinds of  Quality) "Itemcrossing". It can't be deleted, crafted, traded. It just can be in your backpack - or you can crop it too. How does it work? Well, you put your weapon - which you want to start it's journey - into Crafting window, choose "Change quality to : <<Itemcrossing>>", then you need to place it into Action Slot. Then you can drop your weapon(or any other item) on the map at any moment you want. If nobody has taken the item, it return into your backpack. After next player has taken this item, the level of the item grows up (the level is 1, at the beginning), showing how much backpacks it was inside. Also, it could have the name of the starter (the person which made this item "Itemcrossing"). So, you can use this item for your own necessities. Or you can continue Itemcrossing. NB: if you have this kind of item in your backpack, you have a week before it dissapears in your backpack and returns to the starter's backpack. Just play enough and use this item!
-------------------------------------------------------------
Plus I had similar idea: Puzzle Fragments, that are traveling between backpacks. And you need to collect enough parts to solve Puzzle inside your backpack. But there will be special post for this idea, with details (the general part, though, is already here, in these sentences above, under the line).

Project 'Hat Bonus Activator' (for the Action Slot)

This tool (similar to the noisemaker/duels, i.e. with number of uses) give your hat bonus that doesn't affect gameplay very much. It works during N (for example, 1-5) minutes.
Here I want to try imagine possible small bonuses for each existed (at this moment) hats.
