Have you tried out preview-latex (integrated with AUCTeX since version
11.80)?  It displays images in Emacs buffers without blocking Emacs at
all, and renders stuff in the background with a focus on material that
is on-screen.  It works using Ghostscript on either PDF or PostScript
files (in the latter case, dvips is used) or dvipng on DVI files.
Ghostscript is used as a daemon in order to render the stuff in a
useful order, and a single Ghostscript session renders all images.

So it would seem like quite a good candidate for borrowing code.  In
particular since the entirety of preview-latex is already
copyright-assigned to the FSF (as opposed to other parts of AUCTeX
where this process is still under work).
