Bitcoin has a nag, it allows to trace transactions... well, this can be solved by using a concentrator-disperser with a secondary database.

Say A, B and C want to remove traces of their coins, they could upload funds for a central wallet, those funds moved upwards to a central "mixer" and returned at random to each of the 3. Basically what this system would be doing would be to shuffle the coins, so A collects a random amount of coins from B and the rest from C, B from C and A and C from A and B.
Obviously with such a small universe of 3 elements it would still be roughly traceable, but with a significant universe this would allow the total wipe of BTC trace. One receiving the payment from A still could trace back those coins, but as the distribution is done by a separate and opaque database whatever he get from the previous ownership of those coins means nothing for what A has been doing or not.
In the end this is a system to trade btc for... btc.

Unlike traditional banking where clients have only a few account numbers, with Bitcoin people can create an unlimited number of accounts (addresses). This can be used to easily track payments, and it improves anonymity.

Interesting.
So they draw random amounts from a pool? Is there a thought behind A, B and C not getting their own coins back, or should that be possible too? Wouldn't you otherwise be able to guess that somone is A based on the fact that they don't have any A-coins?

Well, now that you talk about it, the random distribution can add some coins of the own to prevent exclusion tracking.
Still, as I said, in the given 3 users' example it would still be roughly possible to track back the coins, but within 100+ not any longer. As A would be getting coins from B to ZD. So A could be C, AC, DC and all other people in between of which he didn't collect coins from.
