Yep, acro distiller is a very different beast. ps2pdf does some format
conversion but basically does nothing. Distiller on the other hand does
stuff like resampling images to the requested resolution, subsetting of
fonts so only the used glyphs are included, merging of duplicate included
images / fonts / functions and other such stuff. The end result is that
distiller does a better job.
Unfortunatly I havn't seen an open-source product come close to it.
