Might be a good move

I don't think you're understanding the thread. There's a hypothetical situation where someone wants to do really weird auth, and we're talking about whether using PAM, which would work with every greeter, is better for that situation, or if it's better to create a greeter that handles the weirdness in the greeter itself. I hope that helps.
