I wondered this too - presumably the last one to be read is taken.  It doesn't 
matter in the case of themes - the first time you install a theme, one is set, 
later on it may change the default, or it may not, but if you have multiple 
themes installed then it's probably because you want users to be able to switch 
between them.

It's more of a problem, as I said, with user appkit bundles.  For example, 
there's no mechanism for automatically installing the EtoileMenus and 
EtoileBehaviour appkit bundles and having them both added to defaults, although 
a metapackage could depend on both and provide a default that activated both.  

I'm not sure what other defaults things might want to set.  It's not a problem 
for apps - they can include their own default settings in the bundle.  It's 
only really relevant for bundles.  The various -back bundles would probably 
want to set themselves as the default back end on installation but, again, it 
doesn't really matter much if you need to explicitly configure which one to use 
with multiple back ends installed - each can install a .plist for itself, and 
if the administrator installs two then he can add a line to 
GlobalDefaults.plist to specify the default one to use.
