Hmmm...got any other links?
I've done some looking into this topic for my own apps, but it seems prohibitively difficult to try implementing this without OS support for it built in. Any app-level links?
---------------------------------
A stupid despot may constrain his slaves with iron chains; but a true politician binds them even more strongly by the chain of their own ideas;...despair and time eat away the bonds of iron and steel, but they are powerless against the habitual union of ideas, they can only tighten it still more; and on the soft fibres of the brain is founded the unshakable base of the soundest of Empires."
Jacques Servan, 1767
