Dumb endpoints is a huge change from the design of the internet (and 
ARPAnet), with a dumb middle and smart ends:  I suspect the original 
commentator was talking about mere /relative/ dumbness...

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 (;-))

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.
