  We show that the log canonical bundle, $\kappa$, of $\bar M_{0,n}$ is very
ample, show the homogeneous coordinate ring is Koszul, and give a nice set of
rank 4 quadratic generators for the homogeneous ideal: The embedding is
equivariant for the symmetric group, and the image lies on many Segre embedded
copies of $P^1 \times P^2 \times ... \times P^{n-3}$, permuted by the symmetric
group. The homogeneous ideal of $\bar M_{0,n}$ is the sum of the homogeneous
ideals of these Segre embeddings.
