I've written a Greasemonkey script that does pretty much what leftcoastbob suggested
here.
It adds a few refinements: the replacement name is "Poster" for the Poster and "Comment N" for commenters, where N is the number of their first comment in the currently viewed thread, so if the same commenter posts more than once in the thread, all his comments have the same replacement name.

As it's a bit lengthy for a comment, and as the pre tag doesn't work correctly in comments, I can't post it here. Email me for a copy.
If anyone would care to host it, that would be great too.
