And yet, it honors "others" permissions?  I can set the r
bit on others, and the cat then works...

to elaborate: group permission is not implemented by any
kernel file servers in the standard distribution.  only a few
non-kernel filesystems bother with group ownership.  all
of them are fileservers that store files on disk (e.g. fossil,
kenfs).

in theory, one could, involve the auth server in the process,
so that a user could use the auth serve to prove he's part of
a group, but nobody's done anything like that yet.
