Digital BW, The Print

What ever happened to the Nanochrome inks? Just spent two hours going
back through old posts to see if I had missed anything on any dye
inks, and ran back across the Nanochromes. Inkvillage seems to be
gone, and I don't find any other solid references on google.

I remember that there was word of changing manufacturers to get it
right, or on changing the formula to make it better, but nothing in a
while. Just wondering if anyone has kept up with John and what he is
working on to see if there is something else to be had.
