This is great data, Ben & Eric. I'm a little worried about the "follow until" in terms of performance (probably not really an issue most of the time) and vulnerability to other modules corrupting state (for which mod_pagespeed would be blamed loudly on twitter :)
So I'm still thinking of the using an early 'create_request' hook so that we can propagate our 'notes' incrementally, but we should certainly be using request->main in combination with request->prev to do the propagation if that's the right thing to do.
