lots of questions on this thread that go unanswered

The lack of information is currently a detriment to this coin, and the relevant information changes every few weeks

so I'll try to answer a few things, I am not affiliated with Anoncoin, just been having my team research it for the last few months:

The Zerocoin "bloat" problem has been solved. First of all, it isn't that large of an addition to block sizes, and second of all, they get deleted or pruned from the blockchain after X confirmations. This completely mitigates any problems that were imagined with zerocoin blockchain size.

Regarding I2P - not really sure. I know a lot more about TOR than I do I2P. I do not think you need your own I2P client running to use Anoncoin in I2P
