Here is an example of the beginning of the thread with indentations using a table. Only author links are used right now. Links to parent comment for each comment could be added, for example.

Though, looking at it makes me think that presenting the whole thread like this is not very readable at all. If a larger audience is the aim, I wonder if a more complete rewrite is not in order? With very good comments quoted, of course. Who is it that will even begin to read the monster document that would be all 118 comments?

Anyway, if we want to reformat the thread in its entirety with some kind of formatting for readability, it should be quite easy to generate many possible documents (in different formats, even) using some quick and dirty perl.
