Russell,

Did you mean to set the parent directory with the GUID bit set? If you 
want files inside the
directory, then chmod the parent directory to 02770.  This will set the 
unix permissions to

 >chmod 02770 .
 >ls -la
drwxrws---  owner group 4895 .
Note the s in place of the x in the group triplet.

So when a file is created by a member of group group, the permisisons 
are set 660.

-rw-rw---- member group 463764  newfile

Caveats: member is member of group group.

Who's on first, anyway.
