Indeed, unfortunately they never shared their code.

As far as rendering in HTML is concerned, a while ago I found this
jsMath library:

http://www.math.union.edu/~dpvc/jsMath/
(examples:
http://www.math.union.edu/~dpvc/jsMath/examples/welcome.html )

which basically turns the rendering of the equations into a client-side
issue (just check out the source of those pages).

For the PDFs, the rendering would still need to happen on the server.
For this, see the thread titled "Incorporate equations in daisy wiki"
form March 2006:

http://lists.cocoondev.org/pipermail/daisy/2006-March/thread.html

which suggests to render the equations as bitmaps. Ideally they would be
embedded as vector graphics, but embedding PDF graphics is not supported
by our PDF renderers.

None of this is a simple "how-to", but maybe it can help you get
started.
