If I told you that you can effectively PM as almost anyone, would you be interested?
Well? What would you pay for something like this?
It's not as simple as it sounds, but very doable.
Implications:
Spread FLPs wider (Send FLP to friends of a user).
Revenge.
Showboating.
As you know, I don't use FLPs. I don't often showboat. I also don't usually look for revenge. I can't think of any way this could be useful to me. I've had it for a while now, and I figure it's about time to put it to use.
Edit: You would pay and then be allowed to request around 10 uses. More money for more uses. It takes a lot to setup a single usage, so 10 is actually quite a lot. What's your price?
