Answer 1

You will need to use a file system that supports ACLs. As mentioned in other answers, the pub and priv group ownership is possible with the basic Linux permissions, but to grant access to the god group, since files/directories can only have a single group tag, will require an ACL. Most of the current file systems should support this functionality - see the manual pages for getfacl and setfacl.
