The network hardware vendors tried this and their strategy failed, it might have delayed it, guess what will happen to an ISP or other network provider that doesn't do IPv6 ?
I actually heared, China has some of the biggest installations of Carrier Grade NAT.
Maybe because Windows XP is still used which doesn't have IPv6-enabled by default (and no GUI to do it) they thought it would be difficult to support IPv6 for those users ?
1. As mentioned by others, people would still need to upgrade their hardware/software to work with it.
2. we already had fixed to extend the life of IPv4: - Classless Inter-Domain Routing (CIDR) - Use of private network addressing / NAT - Name-based virtual hosting of web sites - Tighter control by regional Internet registries on the allocation of addresses to local Internet registries
3. the other thing people keep mentioning is reclaiming the large legacy IPv4-address blocks from for example Apple and HP.
As the Internet growth is still accelerating, it turns out that if we do that, it will only extend the life of IPv4 by only a few months
Which computer,..? Well, with IPv6 privacy extensions enabled (which is the default in most operaring systems) a new random IPv6 address will be generated at every startup or every 24 hours.
So that is hardly useful at the server to distingues between client computers.
There is already something called IPv6 privacy extensions, which is enabled by default on most operating systems, and it will create a random IPv6 address ones every 24 hours which it uses to connect to other hosts.
In Windows XP (if IPv6 is enabled), Windows Vista, Windows 7, newer Mac OS X, newer iOS, Android, newer Ubuntu IPv6 privacy extensions are all enabled by default.
So it is pretty much the same privacy-wise as IPv4.
(Just checked and Fedora does NOT enable privacy extensions, not sure why)

Actually you can't turn it off, because Opera Mini isn't a real browser, that is the whole point of Opera Mini. It is just a client which displays what the Opera server prerendered.
Actually, the fairly populair Spotify uses P2P protocols to distrubute (part of) the content to users as well.
So, ironically, if you block P2P protocols you'll more than double the price of Spotify and people will stop using it even though Spotify is one of a few working solutions of the music industry.
Do you really believe that Linus would use GPLv3 for the kernel ? You most be kidding. Linus is very clear about why he does not want GPLv3. He is happy with GPLv2.

On the Google IPv6 statistics, it says in Romania IPv6 is faster than IPv4.

Maybe you should try this on your desktop machine instead:

It should by pass a NAT router just fine.
Maybe people it relative.
Comcast is the largest access provider in the world and they are busy rolling out IPv6 to more and more customers as we 'speak'.

bing.com and yahoo.com don't return a v6-address, but they both are only a redirect.
www.bing.com and www.yahoo.com do return a v6-address.
Well, that is at least one thing that the World IPv6 day actually brought us.
Facebook, Google/Youtube, Bing, Akamai, Netflix and others now all have IPv6 enabled and they are going to keep it that way.
So pinging ipv6.google.com isn't needed anymore, you can just ping www.google.com ;-)
And there is nothing to change in the browser, the websites all look the same anyway.

What privacy concernts ?
In Windows XP (if IPv6 is enabled), Windows Vista, Windows 7, newer Mac OS X, newer iOS, Android, newer Ubuntu IPv6 privacy extensions are all enabled by default.

I should add that ZFS uses more CPU.
I did a quick test with 2 identical VMs on my desktop with Intel SSD, I installed the ubuntu-zfs as from the article and I installed btrfs-tools.
The VMs have 4 CPUs and 4GB of memory, 3 virtual disks.
The btrfs has RAID1 data and meta data, the ZFS setup used RAIDZ as in the article:
mkfs.btrfs -m raid1 -d raid1 /dev/vdb1 /dev/vdc1
(I needed to create the partitions, for some reason the ZFS version didn't want to work without it)
My quick stupid test, create a large file:
ZFS:
500+0 records in
500+0 records out
524288000 bytes (524 MB) copied, 16.8489 s, 31.1 MB/s
real 0m16.853s
user 0m0.000s
sys 0m0.480s
btrfs:
500+0 records in
500+0 records out
524288000 bytes (524 MB) copied, 15.232 s, 34.4 MB/s
real 0m15.234s
user 0m0.000s
sys 0m0.640s

Actually, i tried that, it give me an error.
Sun doesn't exist anymore, it's all Oracle now.
Interresting enough btrfs works really well on a phone.
I do know kFreeBSD atleast supports ZFS, pf, pfsync and carp from OpenBSD which are all part of FreeBSD kernel.
Not sure about DTrace, haven't tried that.

The question was: why not Linux for security.
You answer is: MS skills ?
I know businesses don't really care about security, but still finding a good admin with MS skills has to be atleast as hard as finding a Linux admin.

Why not ?
Lots of peope get cardiac arrest and they get the heart running again.
Some people even get pronounced dead and "wake up" in the morgue.
So yet, there are people who were dead at some point in their life.
And it isn't just because of the ads, it is also their own content. Some jpg's are loaded from the same hostname over http.
Any version of IE and Safari (and very old Chrome) on Windows XP and the Android browser on any Android 2.x do not support SNI.
So that doesn't make SNI very useful on the public Internet right now. :-(
Which is perfect, it prevents a Network Intrusion Detection System from preventing the attack. ;-)
