Digital BW, The Print

First, thanks to Sergei and Clayton for their helpful responses to a 
question a while back...

What sort of RIP or other programing would be required to set up the 6-
color R200 to run a matte black for BO in one cart, photo black (for BO 
on RC paper) in another cart, and a 4-color set in the remaining 4 
carts? I'm thinking in terms of the 2 Media Street pigment black inks 
loaded so that I can print BO on either matte or RC paper without 
changing cartridges, and still have the ability to do a little color 
printing from time to time (I'd like to be able to print some duotone 
and lith-effect images I've been working on).

Is this possible, or practical? Or should I just get a 2nd R200, or 
even a 3rd---they're so cheap--each dedicated to a particular mode? 
Space IS an issue...I've pretty much run out of clear horizontal 
surface as it is.

Any thoughts? Thanks, -Lee
