What is the current develop progress status?
Is there a time schedule for next releases with new features?
The development status is "in progress".
Currently it's the new codebase (from Bitcoin 0.8.3.7) that is under development. Feel free to watch the development here;
https://github.com/Anoncoin/anoncoin/tree/master-0.8Release dates are not yet out. We're currently discussing a maybe backport on the IRC seed, with support for Irc2P, or another IRC server inside the I2P network. And maybe a kind of coincontrol in the Qt gui which we are currently looking into. We're aiming on a bigger feature list before another release, since we don't want to spam our users with new small releases to often.
Mac OSX users will probably get a early release of the new source once the Qt linking problem is solved. We're currently researching some odd problems where the bundled Qt dylibs requires system libraries that usualy don't exists on OSX installations, which makes the client crash. So that's 1st prio at the moment. (Daemon on OSX is working fine however)
I hope the developers are aware of such issues.
Of course we are. Both I, K1773R and BroTroxer have had discussion on this. Implementations of zerocoin, coloredcoin etc have been discussed. And you will probably see one of the features in Anoncoin in the future, and if none of them, another system that's similar and does the same job. No schedule is set on this. However, the latency problem is known, but not addressed yet. Note, none of those features will come in the next release, but probably the next after this.
Feel free to join us at #anoncoin (IRC, Freenode or I2P)
