LRT, that's another really good one. Saying "Hmm, it doesn't sound like we're going to agree about this right now; let me think about that and we can discuss it later when we each have more time" or something is a great technique.
I added that first part because the key to these techniques is to FIRST let the person know that they HAVE BEEN HEARD, even if you disagree with what it is you've heard them say.
"I hear you saying that you feel ________ . I understand. My feeling is __________ , I feel strongly about it, and it sounds like we're going to have to agree to disagree about this right now. Let me think about it some more. We can talk more about this later."
