Absolutely. Having been a co-designer of ARP, I can assure you that
such a use was not in the minds of Dave Plummer nor I.

No. We had our hands full merely getting stuff to work; protecting
bozos from themselves was an un-affordable luxury.

I'm not sure people really grasp how under-resourced the internetting project
was back then. A lot of things we _should_ have done only got done later
(e.g. dynamic host configuration), or not at all. The hordes (how appropriate
a word) of programmers who are busy writing networking code these days were
beyond envisioning.
