UUIDs have the advantage that they are well-understood and widely supported. If you really need to shave a few bytes here and there, developing your own coding scheme is useful. But for the most part, I don't see the win.
Locality is definitely important, but I must be missing something -- if lookup by date, machine ID etc is required, why not create indices on those fields? Why rely on coincidental locality?
