fine, except I want to remove a certain key/value pair from the

Is there any way to do this? The best plan I can come up with so far
is to read the old defaults from its plist into an
NSMutableDictionary
then add all the keys to the app domain (except the one I want to
remove). But there does not seem to be any API to get
~/Library/Preferences/foo.plist in a nice localizable way...
Definitely don't access the .plist file directly.
I'll second this. :)
One approach is to drop down to Core Foundation's CFPreferences API.
This is the smallest hammer to use; CFPreferencesSetAppValue() is
probably what you want here.
Another is to use the "persistent domain" capabilities of
NSUserDefaults. Pull in the dictionary for the domain, make a
mutable copy, modify it, and then write the whole domain back out.
This is overkill; use the CFPreferences API instead.
