Digital BW, The Print

Now and then someone is talking about printing the new 
piezotones via the IP4 RIP. I´m not aware of any special update 
nor have I seen piezotone-profiles on the Colorbyte web site.
So, how do you manage it?
Do you simply use the old cone profiles  or the MIS FS profiles, 
or are you ß-testers again?
