I understand the benefits of EPUB, what I don't understand is the need
for TeX at all. (X)HTML is dynamic by nature, you should be able to
resize or change text size and the layout will re-flow, forcing a rigid,
box based layout that is a direct translation of TeX output just does
not make much sense to me. I've the feeling that you are looking for the
wrong solution to the problem. One of the strengths of TeX that I mis
in almost all HTML renderers is decent line breaking and hyphenation
algorithms. While I don't know any any HTML engines, especially
implementations of TeX's line breaking and hyphenation algorithms,
compromise. See  for example (some interesting links near the end,
