      Craig,

   Barry covered things pretty well.  The only other issue which comes
to mind is that many IPs derived from BSD code allow you to set a
"subnets are local" flag.  Setting this flag causes the code to generate
MTU sized datagrams rather than 576 octet datagrams for all subnet
destinations.  In most subnetted environments, this is a significant
win.

				Later,
				    Bob
