What the heck is a Hacker Pantry?

In the Shirokanedai house for this proposal, there is the awesome sort of half room, between the kitchen and the bathroom before the genkan. I imagine it as a Hacker Pantry.

A room of shelves, where the members can store both collective anyone can use stuff and tools. AND a personal bin with each hackers name on it for the hands off mine mine mine stuff.

Size of the Hacker Pantry = 5.9 sqm / 3.1j
