NFS permissions

Hey gang --

I solved the NFS puzzle, it seems like NFS treats
<machine, username, usergroup> as a triple for
authentication -- so a root:root on one machine is
not the same as root:root on another! Thus, you
can only _start_ writing to world-writeable
directory on the remote machine, but then can do
whatever you want in the subdirectories you create
there. Ha. So when NFS-HOWTO says the username
and the group must coincide on both machines for
the right access, they probably forget to say you
should come from the same machine and only can
writeover stuff you put there yourself; also, you
can start putting stuff only in a world-writeable
directory on the remote site. Am I correct? I
made it work, yes, nay I'm curious about the
general rules. E.g., how NFS know I came from the
same machine.
