this is an area that has long interested me as well. its also one
of the reasons i like the old ftn tech that bbs offers although
unless we find non internet dependent ways to shift packets between
nodes i fear any deliberate attempt by a hostile force to cut
marine cables currently carrying most global net traffic would
quickly silence this and any other ftn hobby network :-(
 
Although it would not necessarily help if someone cuts cords
somewhere, I do still maintain a dial-up node with Binkleyterm answer 
ing the calls.  It does not currently have a Zone 21 address
associated with it, but it always could.
