If only they could generate the initial parameters in a trustless manner. NOBODY who cares about privacy is going to use a coin created by academic researcher funded by the US Department of defense in a system where TRUST must be given to the devs to throw away the master key. That is why zerocoin is superior. Yes there will be bloat issues, Yes the transactions are slower. But at least we will have trustless anonymity with RSA UFOs used to generate the initial parameters. All of zerocash's advantages are for nothing if the gov't has a private key that unlocks all anonymity and enables unlimited minting of coins.
Just to play Devils advocate...
I believe the trust issue has to do with unlimited minting of coins, and if someone were to have the initial parameters they will not be able to break the anonymity.. that is at least what Ian from the Zerocoin/Zerocash project stated on Twitter, so the bolded statement is wrong.
Also it seems that the Zerocash parameters can be generated in the same way you guys have implemented the tea ufo project by the use of multi party computations.
I also read that it is not a case of having to trust everyone involved in the creation of the initial parameters was honest, but you only need to trust that one of them was honest. If 20 people had a part in creating the initial parameters, then you would only need to trust that at least 1 out of those 20 people were honest.
These are almost direct quotes from Ian and Matthew from the ZeroCoin/Zerocash projects.
That being said, Zerocash/ZeroCoin has not been able to release a working product yet, so I think it is good projects like Anoncoin are implementing Zerocoin themselves. There is no way of knowing if Zerocash will come to fruition in a sufficiently trustless manner anyways.
