Its funny how the extra inkjets present a dilemma on what to do with them.
The traditional Piezo solution has been to just double up and duplicate two
of the inks.  There is no benefit with the duplicate inks, but given the original 
plugin or the Epson driver with ICC profiles there's no way to take advantage
of the other inkjets.  With a RIP that controls the inks separately it opens up
the possibility of using the extra inks in some creative way.

The natural thought is to have two colors available but with only 2 extra inks you
don't have room for another complete set of piezotones.  I think there are a
few people that have tried some of the possibilities.   You could just use
two of the sepia set -- and as long as you blended the output with the
full selenium set you would probably get a nice smooth result.  This will
probably allow you a mild variation on the tone from pure selenium to a
reduced carbon sepia color.   If you get into mixing inks the possibilities
are endless.
