	I believe the specifications also require all networks to be able to
	forward a 576 octet datagram without fragmentation.
	
No, I don't think the specs say that.  We certainly advise AGAINST 
networks with MTU's < 576 for performance reasons, but historically 
there have been several... Packet Radio Net and SATNET, if I remember 
correctly.   If people implement the protocols correctly, communication
should still function across a network with small MTU.
