For AMPRNET (Amateur Packet Radio Net, #44), some are questioning whether
getting a class A address was the best thing at this early development stage.
Having a class A address makes internetworking Harder in our case, since
a network is assumed to be fully connected internally.

AMPRNET is not, and probably will not be for the next few years.

So my gripe isn't with the size of networks as much as the (presumed) model and
the various implementations of it. I'd rather glue things together with smart
AMPRnet<->Internet gateways (I believe that they should be the only machines
with the burden of keeping detailed routing information for AMPRnet.)
