LuaTeX comes of age

Yes, tex4ht uses real TeX interpreter, it only inserts html codes in some macros such as sections or lists to add some meaning to the output. It also supports conversion of generated DVI to images, which is useful for various diagrams.

I've also created experimental project which uses Lua callbacks instead of the DVI processing, but the downside is that it doesn't support tex4ht features which requires some DVI tricks, such as the image processing or some tricks with math.
