Hi Andrew

I'm not sure that's correct. As I understand, a file with 0660 should 
have group rw. However, under xp and win7 the same file gets 'Access is 
denied' for group members. Also, a 0750 share should allow only group 
members to enter. Under windows, anyone can enter, group member or not.

Does s3fs understand Linux permissions right now?
Can I control access using s3fs?
