Any port in a storm. I can convert from RGB to CMYK easily using 
Imagemagick's convert program but that converts everything to a 
bitmap. Not wonderful for text. I can convert to the near-
mandatory pdf x/1-a:2001 format (more and more USA digital 
printers are specifying it) using the shareware progam 
Pstill but that costs money and I don't know what if anything it 
does to color models.  I can import into Scribus and export, which 
handles color models but doesn't (yet) offer the PDF X/1-a format.

One of the goals of ghostscript is or was to make Acrobat Distiller 
unnecessary for most of us.  Addressing color model and pdf 
format questions mentioned above would be a big step toward 
that goal.
