This seems like overkill, since it sounded like he was talking about
using Samba as his file server.
The easiest solution is to tweak these settings in /etc/samba/smb.conf:
; File creation mask is set to 0700 for security reasons. If you want to
; create files with group=rw permissions, set next parameter to 0775.
create mask = 0755
; Directory creation mask is set to 0700 for security reasons. If you want to
; create dirs. with group=rw permissions, set next parameter to 0775.
directory mask = 0755
