By setting aside 15% of the budget for demurrage that would give us 3.25 years until "supernova" when the foundation has to start taking charges to the distribution accounts. This is close to the proposed lifespan of the foundation. The foundation is designed to die. Its sole purpose is to distribute the coins and then to dissolve.
Both Ripple and FreiCoin are experiments in how much the crypto-coiner community is willing to trust a central non-miner initial distribution. I think FreiCoin is one step ahead with the publicly announced 3-4 year period of the foundation managing the initial distribution. And also the clever way it is done, not through pre-mine but rather a percentage of each block (which enables the foundation to limit its holding of FRC throughout the distribution period.
But Ripple has started it distribution in the give-away thread here in this forum. No faucet or any grant has yet been made by FreiCoin, as far as I know. So +1 to Ripple for having an early faucet/give-away.
