Freicoin: Demurrage Implementation

[cc5alive]

Does anyone know how the Freicoin demurrage will be implemented?  Is the 4.89% an annual tax at a set time?  Or is it a year from the time the coins are received?  Something else?

If it's annual, coins will become a little less valuable prior to the collection.  If it is from the time the coins are received, it would still be easy to evade the tax by trading coins in and out of you wallet.

I've thought of some other versions of how it's implemented, but they all seem to have some flaws... but I'm not against the idea of demurrage either.  It is an interesting approach to distinguish the currency and try to support the idea of a transactional currency.  Anyone have any insights?

The demurrage is aplied in every block.
Every new block will take a few satohis from your wallet.

How does it calculate which satoshi's to take?

If I have a wallet full of freicoins that I loaded up 2.99 years ago, and deposit all of those freicoins into an exchange... will the exchange have every single freicoin revoked at 3.00 years?

There's a calculation, that I don't remember(go read the white paper!), but it's ~4.9% of demurrage in one year of the total value of your wallet.
