Lily's last conversation with Voldemort just so happens to replicate the requirements of a Dark ritual - you name the thing sacrificed, and then the thing to be gained.
I've always considered the protection Harry had by Lily's "Love" (in canon) to be essentially dark magic done by Lily. She spent her own life to cast a ridiculously powerful and specific spell of protection on her son. The 'power of love' nonsense is true only in the mundane sense of the term. It was the motivation to use the spell. This doesn't devalue the power of love - that's how love really works - it influences the incentive of intelligent agents.
How much of this is Dumbledore actually guilty of? Do we know or suspect other trickeries, or have other evidence?
I wouldn't place this one in the realm of 'guilt'. Assuming things happened according your story, Dumbledore gave Lily the power to do something that she wanted to do (sacrifice, save). Helping other people save their babies does not accrue guilt.

I like that. Definite improvement over canon.
The new thread, discussion 13, is here.
This is a new thread to discuss Eliezer Yudkowsky's Harry Potter and the Methods of Rationality and anything related to it. With three chapters recently the previous thread has very quickly reached 1000 comments. The latest chapter as of 25th March 2012 is Ch 80.
There is now a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author's Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.)
The first 5 discussion threads are on the main page under the harry_potter tag. Threads 6 and on (including this one) are in the discussion section using its separate tag system. Also: one, two, three, four, five, six, seven, eight, nine, ten, eleven.
As a reminder, it's often useful to start your comment by indicating which chapter you are commenting on.
Spoiler Warning: this thread is full of spoilers. With few exceptions, spoilers for MOR and canon are fair game to post, without warning or rot13. More specifically:
