Yes, that is my understanding exactly, except I have read over and over that it is only possible to generate trustless parameters with zerocoin, not zerocash. Do you have a source that states it is possible with zerocash?
I am just going off of what they have stated on Twitter. Along with the following statements, they have mentioned the ability to generate the parameters by using multi party computations.. which is basically what the rsa ufo project is doing with ZeroCoin. If you look through their statements on Twitter it doesn't sound much different than they way Anoncoin is computing the ZeroCoin accumulator.
Re: Trust required for Zerocash setup


Maybe I am naive, but I think they will find a way to setup Zerocash that people will be able to trust.
Well that is interesting, But I think unless they are able to pool hundreds of people to publicly generate the parameters in a trustless manner I kind of doubt the darknetmarket people will use zerocash over zerocoin. I'm willing to bet money they would trust meeh over matt green et al.
