I take it a network drive for /bin, /lib, and /usr is not an option?

The same way setup.exe handles them -- if replacement fails, schedule one
on reboot. Someone posted a perl script for getting those out of the
on-reboot replacement list; I'm sure you can use similar techniques for
getting them on that list.
But I would go with the shared network drive approach, if at all possible.
