Interesting that he thrust of current IRTF delay-tolerant<BR>
networking work has effectively turned your statement below<BR>
on its head, in believing that there is no need for reliability<BR>
at the top of the network, and no need for location at the top<BR>
of the network, either.<BR>
<BR>
How the network base assures sufficient reliability and assures<BR>
that endpoint identifiers map to something meaningful would seem<BR>
to be open problems...<BR>
