I really like the Skill Extractor idea and the mechanics behind it.
I wish that CCP would allow us to do something similar with LP where we go to the LP store of a faction/corp that we have LP with and let us buy something that can be redeemed for LP. They can be bought in incriments of 10k LP for a small and 50k LP for a large. This LP injector/tag item would then be sold on the market and can be bought and redeemed by a purchaser at a store for LP. These items would be physical objects that are hauled and can be ganked.
Just an idea.
