Thanks for the extensive feedback John, this will be most useful when looking into BP-compatibility.
But to make sure your (and those of occasional readers of this thread) expectations are correct; Autoptimize might (will?) not always work out of the box for all of the javascript-"widgets" you mention. In those cases tweaking (as described in the FAQ under "Configuring & Troubleshooting Autoptimize") will be required by the blog owner him- (or her-)self.
