I'm coming back to it finally, sorry for the delay.

* "Tails 0.1.6." -> "Tails 0.16"
* Tails has not been available as a LiveCD for a year or so

About Whonix supporting "any" hardware: I don't think this is
compatible with claiming to ship the Torbrowser. Rather than such
a broad claim, perhaps clarify that Whonix supports any hardware that
is able to emulate an architecture supported by the TBB binary builds?

Thanks for the heads up. Added as "3.6.13 Iceweasel" on our design
doc. But that comes with 0.17, so you might have to update other
parts too.

Yes, perfectly.

OK, I see :)

Nice. I'd rather see this called "a modified Tails" rather than
"Tails", though.

I'm not sure what you mean. In any case, "3.3 Internationalization" in
our design doc might help.

"Requirement to fit on a CD." => CD, really?

"Isolating Proxy for strong IP/DNS leak protection." => why does the
comparison that follows holds for *DNS* leak protection?

"Remember installed packages." => upcoming in 0.18.

I'm still quite sad to read FUD like "adrelanos would have to obey the
Tails developers decisions, otherwise contributions do not get merged"
spread about Tails. I call this FUD because:

  a. Using "to obey" suggests there is a strong authoritarian
     structure in the Tails project, while I've never seen anyone
     dictate anyone else what they should do, and ask them to "obey",
     in this context (save various trolls that try to dictate what
     we're going to spend our time on). I don't mean we're living in
     a fantasy world where we're all perfectly equal, but I absolutely
     disagree that our decision making process works the way you
     put it.


  b. It suggests there are "the Tails developers" and... the rest.
     It's true that there are various more or less "core" developer
     status, with different commit bits, different levels of access to
     sensitive information, but there are certainly not two such
     binary categories.


  c. By affirming that strongly that one has to "obey" else
     "contributions do not get merged", it suggests that there are
     precedents of this process. Reference needed.


"Video/streaming software." => on the one hand, you make it clear one
may install such software on Whonix; on the other hand, you point to
a Tails ticket. That kind of unfair / differentiated treatment sounds
like cheap advertising to me; it's not an isolated case, and to be
honest, it certainly does not make me happily anticipate reviewing
such documents again. I wish that next time, you apply a filter for
differentiated treatment first, before asking for reviews. Anyway,
that's your call :)

To end with, perhaps drop the sub-sections where Tails and Whonix are
on par?

> Thanks for reviewing!


Np. To be clear, I did not review these pages entirely last time,
and I only skimmed through it quickly this time.

Cheers,
