[Zope] Anyone Working on an Equation Display Mechanism for Zope?

Is anyone developing a way to display mathematical equations on a Zope-base web site? I'm wishing for something along the lines of an eqn->troff->ghostscript->gif_tile pipeline. It'd be neat if there were a ZEquation product that took a blob of equation text and when used in a link, provided a GIF tile of the equation neatly laid out. I can't expect the Zope engine to fork off a whole series of special tools in a timely fashion, so maybe a background process could scan the ZODB and insert the GIFs in some form of folder cache, using the timestamp of the ZEquation instance and a timestamp on the GIF cached item. Ideas? An easier way? -Jeff Rush
