Noneone is acting like it can be implemented anymore, we are going to implement just a mixer. Besides, I head rumours that it's going to be open source on May 25th.
If so, that is sooner than I expected. I thought on the 25th they were simply going to do the masternode payment fork ... didn't see anything about opensourcing on that date. But look back one page (or right above where I posted) and you see things like this:
omg

with darksend or similar arrive at 100k sat

We could go much higher than that, but we'd need a really incredible developer.
There were some talks earlier today about new developer coming onboard to implement darksend into libertycoin.
That was what I was referring too... people acting like they can add it now.
It cannot be added now.
