10:59:49 wumpus | so, darkcoin is basically bitcoin core on an altchain with a coinjoin implementation slapped on top, but it seems they don't release the source of the coinjoin part (at least I wasn't able to find it in their repository...).. that tactic smells a bit fishy to me, although they're probably afraid of the ease with which it could be backported to bitcoin :-)

Is this true?
There is nothing fishy about it. DarkSend will be opensourced once it's finalized.
