Sorry for the cross-post. Having give it some additional thought, I  
realize now I should have posted this here first ;-p

I want to lock down my site as much as possible and would like to set  
the file permissions as restrictively as possible.

Is there any reason that any file used by my app but not in the /public  
directory or subdirectories needs or should have Read, Write, or eXecute  
for Public permissions?

How much can I lock down the Group permissions? Or does that depend on  
the hosting service?

Thanks,  
Bill
