In post #23, Infiniti2000 would seem to disagree with you, H-Smurf.

Or that they only unarmed strike while FoB?
Correct (or use a special monk weapon). This is stated quite clearly, and explicitly. Unless you can argue that you can use an "unarmed strike" to grapple, a monk cannot grapple while flurrying.
I don't buy that for a minute- a monk (or any PC, for that matter) should be able to unarmed strike at any time they can do a regular melee attack.
As things stand under the FAQ ruling, Disarm, Grapple, Sunder, and Trip are all valid uses of FoB and other unarmed strikes. The answer does not address a distinction between unarmed strikes and unarmed attacks.
Under attack!=strike dichotomy, unarmed attacks
(which do no damage) can be used for: Disarm, Grapple, and Trip attacks...except that Grapple gets a bye and can do damage as an unarmed strike.
Grapple thus seems to occupy a middle ground as an unarmed attack that can do damage...except that it is never defined exclusively as an unarmed attack or an unarmed strike. It is unarmed, yes, but whether it is "strike" or "attack" is never explicitly mentioned. Which it is, we simply don't know. Thus discussion of it isn't helpful: it may be an unarmed attack that does damage like an unarmed strike, or a combat maneuver that does damage like an unarmed strike because it is one.
Now, we've already established that:
1) RAW, unarmed attacks do no damage- there is no data in text or chart describing the damage an "Unarmed Attack" does. Unarmed strikes, yes, but not unarmed attacks.
2) We have the language of Ki Strike:
Ki Strike (SU)
At 4th level, a monk's unarmed attacks are empowered with ki. Her unarmed attacks are treated as magic weapons for the purpose of dealing damage to creatures with damage reduction. (see Damage Reduction, page 291 of the Dungeon Master's Guide). Ki strike improves with the character's monk level. At 10th level, her unarmed attacks are also treated as lawful weapons for the purpose of dealing damage to creatures with damage reduction. At 16th level, her unarmed attacks are treated as adamantine weapons for the purpose of dealing damage to creatures with damage reduction and bypassing hardness (see Smashing an Object, page 165).
Keeping in mind point 1, and assuming attacks are not synonymous with strikes, we have a section that effectively says:
Ki Strike (SU)
At 4th level, a monk's unarmed attacks (which do no damage) are empowered with ki. Her unarmed attacks (which do no damage) are treated as magic weapons for the purpose of dealing damage to creatures with damage reduction. (see Damage Reduction, page 291 of the Dungeon Master's Guide). Ki strike improves with the character's monk level. At 10th level, her unarmed attacks (which do no damage) are also treated as lawful weapons for the purpose of dealing damage to creatures with damage reduction. At 16th level, her unarmed attacks (which do no damage) are treated as adamantine weapons for the purpose of dealing damage to creatures with damage reduction and bypassing hardness (see Smashing an Object, page 165).
edits and emphasis mine.
While the original text would seem to imply that all of the monk's unarmed attacks are enhanced by Ki Strike, this clearly cannot be the case unless Unarmed attacks = Unarmed strikes. A Ki Strike no more enhances the non-unarmed strike unarmed attacks than my prescription glasses would help a blind man see. The supernatural ability enhances the ability to do damage...and unarmed attacks RAW do no damage.
So, we are still faced with a conundrum- either unarmed strike!=unarmed attack (as in the former is the subset of the latter) and Ki Strike is poorly worded
OR Unarmed Attacks are merely Unarmed Strikes before the dice have been rolled- the position hinted at in the PHB glossary, PHB p40-41, and the FAQ.
I side with the latter. Ki Strike was clearly using Unarmed Attack as a near synonym for Unarmed Strike, seperated only by causeality. The roll of the dice makes the attack a strike.
