Inventory scripting is something I am working on, BUT it is the type of code that is gonna be custom to many projects, the look / feel and so on, some people want block based system, so like many RPG, your backpack is a set "blocks" that hold items (Diablo style), others want a listing style (Oblivion style), others want a mix of both.
Might be worth putting up what u want and we can take it from there.
