Do you have a feel for how much slower the elisp-based parsing is?  Is it causing noticeable delays in Gnus, for example?

The various legal hurdles/barriers impeding dynamic library use in emacs are (mostly?) overcome, and this seems like a fine potential candidate.  I suspect that ideally we'd have lisp calls that would call a library parser if available and an elisp parser if not.  What do you think we'd want (in terms of speed/convenience tradeoff) in addition to parse-html?  I'd guess that we'd like to be able to parse both a named file and a buffer (but perhaps working on buffers would lose us the speed of the library?).

I can't totally commit to building anything, but I'm interested in the dynamic library interface to emacs (interested but not yet knowledgable), and I might be able to put some time into helping out.

*Chad
