OK, maybe this is a good time to talk about some of that "dialog posing"
stuff, then.

I *think* that it already works this way. As I replied in another post, you can
implement the nsIHelperAppLauncherDialog interface and thereby block or replace the
dialog.
Maybe there's more to this "dialog posing" thing? What are the "three
methods" that need to be added? Do these replace to the business about
being able to control the display so that it uses one's choice of the
default implementation, an alternative, or none (the "Preferential
Dialog Overriding")?
