A unique useful feature is what a coin needs now days to standout in the crowd of clone coins. I don't want Darkcoin to be seen as a clone by loosing this unique selling point.
Completely agree.
If all of the coins implement it, at least their source will say "DarkSend" 1 million times. That's at least better than KGW, which doesn't share the name
I'm all for it being open sourced, just not right away, in 3 months or something around that amount of time, so darkcoin has plenty of space to grow.
