This isn't a resource problem, it's a code problem. The IETF wants
10-15 year old hosts to be able to connect to a network and
perform basic networking. It might not be very optimized, but the
basic function should be there. New functionality can optimize for
different factors, but making older host stop working is frowned
upon.

<p>Fortunately this is a solved problem in capacity planning: you
replace machines often enough that they're not constantly out of
service being repaired. 10 to 15 human-years is the equivalent of
70 to 105 of the dog-years we use in this silly business (;-)) <br>

<p>The oldest machine I use is a dps8-m, and I'll be slightly amazed
if we can provide native TCP. Right now I ssh into the virtual
machine that's running it, all so I can continue to fiddle around
with Multics.</p>
