This is a term invented by Alan Cooper in his seminal work About Face - The Essentials of Interaction Design (buy it; it's brilliant). A program that runs in daemonic posture is one that requires no interaction from the user. Many AJAX-type programs are DaemonicPosture, because they run in the background and only deliver their results to the brower when they are ready. For example, an embedded clock widget runs in this posture.
See this article by Cooper describing the main application postures.
