I need to include a PDF picture in a ConTeXt document that is much too
detailed to be scaled down onto a single page. So I need to distribute it
across two ore more pages.
- Is there a way to display only a part of a PDF file in ConTeXt, like
  it could be done with manipulation of the bounding box of a PostScript
  picture in LaTeX?
Since LaTeX can do it it for PDFs too, it should be possible in ConTeXt
as well. The problem is that there seems to be no option in the
\externalfigure macro for this purpose. Hans knows ...

- Does anyone know an application that will split a PDF file into
  user-defined parts (not just printing pages)?
- Any other ideas?
there is a clip macro:

   \clip[nx=2,ny=2,x=1,y=1]{\externalfigure[koe]}
   \clip[hoffset=1cm,width=2cm,height=3cm]{\externalfigure[koe]}

you can also apply arbitrary clipping paths (see metafun manual)

\startMPclip{fun}
   clip currentpicture to fullcircle
     shifted (.25,.25) xscaled \width yscaled \height ;
\stopMPclip

\clip[nx=1,ny=1,x=1,y=1,mp=fun]{\externalfigure[koe]}
