I can't remember if this has been asked before, but is this a single file, or 
can we scan a directory for plists providing global defaults?  For packagers, 
the latter is a lot more useful - they can then add and remove defaults 
trivially.  For example, when you install a theme bundle, you can set it as the 
global theme, when you uninstall the theme, you unset this default.

This is nontrivial to implement though.  A typical use-case would be installing 
a user appkit bundle - you'd want to add this to an array in defaults on 
install or remove it from that array on uninstall.  Can plmerge or similar do 
this, and is this documented somewhere that's easy for packagers to find?
