Does the Blink spell count as concealment, and deny AoOs?

SRD description of Blink: http://www.d20srd.org/srd/spells/blink.htm
SRD description of concealment: http://www.d20srd.org/srd/combat/combatModifiers.htm#concealment

Although it doesn't specify it exactly, it appears that a blinking character effectively has full concealment, or a 50% miss chance. In addition, the spell blink specifically refers to the concealment rules if the target can strike ethereal creatures:

If the attack is capable of striking ethereal creatures, the miss chance is only 20% (for concealment).

In the SRD section on Concealment, the phrase of interest to this question is:

You can’t execute an attack of opportunity against an opponent with total concealment, even if you know what square or squares the opponent occupies.

My question: Since the blink spell apparently grants concealment based on the above, does a blinking character not provoke AoOs for any action, unless the opponent can either hit ethereal targets or see invisible?

It provides a 20% miss chance from Concealment.

TOTAL Concealment, which denies AoO, provides a 50% miss chance.

So, blinking does not provide total concealment, so it does not help with AoO.

Not really. He benefits from a 50% miss chance, which is partially derived from concealment, and partially from the fact that he sometimes goes ethereal just before you hit him.

If someone can see invisible (which would negate total concealment due to invisibility), they still have a 20% chance of missing you. The 50% is not from total concealment, so the benefits of total concealment do not apply.

On the other hand, the miss chance does derive partially from concealment, so the benefits of concealment - like immunity to Sneak Attacks - do apply.
