Great info all around, Otto.  Thanks for this.

New Question:  Plugin A includes some JavaScript library or whatever  
and enqueues it as "xyz".  Plugin B includes the same library and also  
enqueues it as "xyz".  Okay, through the magic of code there is no  
duplication.  But what happens if Plugin A has an older version of the  
library?  If that gets loaded then Plugin B is stuck with the older  
version.  Is there a way to avoid that?  A way to ensure the newer  
version loads?

(Frankly, it would be cool if there were a way to enqueue a PHP  
library as well....)
