I know this is more of a request for coding help, but just wanted to
add my vote that this would be great. I don't use html *that* much,
but having the option would be awesome, and the replacement of all
*.pdf links with *.png (and typically re-running R code to generate
.png version, or running imagemagick on the dir to create them) is
typically too much of a barrier so I just stick with PDF/Beamer.

I'd love something like this.
