That's an appealing idea, but the devil lies in the details.

I wrote just such a comment system for  draft chapters of our book, and 
it's seen a lot of use.

However, what I do is add ID tags to the DocBook source, and the XSLT 
processor passes those through to the final HTML.  This isn't easily 
generalised to other tools, as each needs its own approach.

An alternative is to embed identifiers in the generated HTML, but this 
is brittle in its own way.  Few people generate HTML by hand, and most 
tools that do so have a habit of making huge changes to the output 
structure in response to minor user edits.  Stably identifying chunks of 
text across multiple versions of a document is thus somewhat fiddly.
