Diverging a bit...how would one connect a few thousand PPP interfaces to
one computer? PPPoE?
(I've never seen more than 8 serial ports per adapter) ;)
Perhaps a tree would be in order (e.g. up to 253 leaves connect to a local
coalater; up to 253 coalaters connect up to another....etc). e.g. one
server per class C network. Then routing is relatively easy; never more
than 254 route for each server to remember.
Thousands of professors at hundreds of universities
teach all manner of subjects, but there is not one
single university chair for research into child abuse
and cruelty to children. How strange, when we recall
that the majority of the people living on this earth
are victims of precisely that kind of treatment!
