I used GeneratePDF for a while, but it still falls short of my goals.

And you haven't seen what xelatex (texlive-xetex) can do using random
fonts installed in your system.

But conversion from HTML to LaTeX is usually lossy and cumbersome.

That's precisely what I am trying to do! My first approach (find it
here: http://www.pmwiki.org/wiki/Cookbook/LatexMarkup) was to use simple
php find-replace:

Markup("emph", "inline", "/\\\emph{(.*?)}/", "<em>$1</em>");

This allows you to pick a LaTeX document and put it into PmWiki. If the
document does not contain overkill features you can configure a series
of rules like these to

a) skip the preamble
b) present in html the known rules
c) ignore the rest or display it as text.

The same way it works with LaTeX input, presneting it as HTML just like
PmWiki markup, it could work for LaTeX output, replacing PmWiki markup
with LaTeX markup and presenting the resulting document between
<pre>tags</pre>. Such behaviour would be associated with a page action
(action=print or action=export, for instance).

But for some reason I can't figure out, if you put a long list of rules
like this, some rules work while others don't. So I was a bit
disencouraged from extending the recipe or from creating the reverse rules.
