My old project Jitify (www.jitify.com) currently does the "html
content optimization" part. It has a set of streaming parsers for
HTML, CSS, and JavaScript, which might be a useful foundation for
adding the "content negotiation cache." There are a lot of
interesting optimizations you can do just by adding hyperlink
rewriting to the HTML and CSS optimization code: image inlining, for
example, or modification of image links to refer to a CDN or a
cookie-free domain. It's unclear when or if I'll have an opportunity
to resume work on it, but the core code is available under the Apache
license, so feel free to reuse any of the code if it's helpful.

Cheers,
