While I dont want to question your enthusiasm, I do question the
sense of this logic. I'm hearing rather emotive reasons having
more to do with the fact that at some historical point in
time people were stingy with ARP code, and made implementations
with faulty assumptions.

Once burnt, never use fire again? You'd have been a very
cold cave man :-)

So on one hand you're happy to write code that branches based
on the 16 bit identifier, but on the other hand you're not.

I'm sorry, but this doesn't make sense. Why do I get the
impression that this reaction to 'hardware type' is a
touchy-feely emotive one due to a desire to differentiate
the glorious NHRP from the ugly ATMARP ?
