diffing binary files/ custom diff filter tool

I know that this question is asked pretty often here(OO.org files in
particular), but I had an idea how to add at least an improvement to the
situation. My particular problem is that I need to diff fonts which use a
non-textual format.
Anyhow, for my case it would be enough if I could have a filter that converted
these font-files to a textual representation and then compare these. I would
then simply take each glyph/character in that font, compute a hash for it
and output that hash and the codepoint to stdout. The users could still not
see exactly how each glyph was changed, but at least they would have more
info that just that the font was changed.
The same strategy could be applied to each member of other archives like above
mentioned OO.org files.

Now, how would I best go about integrating this(Tips for RapidSVN and
TortoiseSVN also greatly appreciated)?
