Yes. The development team is currently having discussions around the forging algorithm. There are a few main considerations of any forging algorithm:
(1) Is it "fair"?
(2) How can people cheat it?
(3) Who will it encourage people to forge?
As long as the transparent forging isn't affected I think we can think about doing things differently. I always thought about taking the "age" of coins into account like I think peercoin does.
(1) Aging will reward coins that have most recently been transferred.
(2) One person transferring coins between N accounts.
(3) Only people with recently transferred coins will be encouraged to forge.
I think you missunderstood.
I mean the "oldest" coins should be more valuable in terms of forging power than "young" coins. So it should be the exact oposite of what you described.
If I have coins and I don't do anything with them for say a week I'm more likely to forge a new block than someone who has just transfered his coins. Once a coin has forged a block it's age is reset so that noone has an incentive to simply hoard his coins forever. Like I said I think that's the POS implementaion of PeerCoin i think.
