Thanks, that was interesting.

He says (re download speed)
    "Ultimately the net outcome of course differs depending on
     specific details, but I would say that for single-shot static files,
     you won't be able to measure a difference."

So in that case, what's minimal, and how vulnerable is it?

Is there a minimal quic without google upstream?

or X.25 -- dating myself ;-P

and what about TFTP/PXE ??

What would the mes-people suggest
for minimalist functionality, and minimal trust scope,
and maximal monopoly-independence, I wonder?

[meta-question] How does one gracefully go off-topic onto a tangential
discussion? I thought my original comment re expired gpg key might
have helped in some way, but my comment wanting to get the ftp fixed
intead of (or in addition to) being bypassed provoked the explanation
of how I was deluded (ok, no worries :), but I might want to
say something about separate connections isolating meta-data and data
as being a "feature" that I expect to see more of, but that would be
another step along the tangent ... or osculating circle? NNTR :-D
