Separation made by XPress and other programs is needed in most cases
today, since most RIPs I know of have in-RIP separation only as an
announced future feature. And many color prints are made using Pantone
colors.

IMHO the downsampling of image files is a key feature of OPI. Only the
scanner operator and the Photoshop wizards deal with big files, but the
majority of people does text and layout, and therefore work with the
low-res files only. This is the only way to deal with these masses of
data we have in prepress environments in an ethernet network.
