[e2e] end2end-interest Digest, s/Vol 53, Issue 10 / sacred cows, sacre bleu/

[Jon Crowcroft]

a perfect example of people responding to email that they havnt actually read properly - the internet is dead
as a human channel since users prefer to write things in response to the control signal rather than the data in the channel
please read the paper which actually disusses 
responses, icmpo and tcp option problems
before creating more noise.

also, 
without even reading the paper, 
you could consider who sent the message and the fact that
they might actually have spent some time thinking about a problem and so might actually
have considered a few OBVIOUS things
such as you mention below....

in fact some other people (e.g. pekka) have also thought about this a bit more so
perhaps you could read their work too....this supports the idea that this is not pointless, 
half baked daft work......at leasr more than being knee jerk dismissiove about it


this is exactly why io dont go to ietf meetings or read any lists any more associated with WGs

its full of "write only" repetition.

if human communiation  needed this level of forward error correction all the time
language would be very different - it is a shame that email has turned into
such a simplex channel
