OK, this is actually easier that you might think...

in /mnt/200 put 2 directories "www" and "shared"

$ mkdir /mnt/200/www
$ mkdir /mnt/200/shared

then make a symlink in /var to these directories in turn.

$ ln -fs /mnt/200/www /var/www
$ ln -fs /mnt/200/shared /var/shared

Who says GNU/Linux was hard ?? (don't forget the config files in /etc)
