 From man chmod:
STICKY DIRECTORIES
       When  the sticky bit is set on a directory, files in that 
directory may
       be unlinked or renamed only by root or their owner.  Without the 
sticky
       bit,  anyone able to write to the directory can delete or rename 
files.
       The sticky bit is commonly found on directories, such as /tmp, 
that are
       world-writable.

What this means is the sticky bit has to be set on the parent directory, 
which in your case is the directory being shared.
