You need to compare apples with apples. I'm saying that the feat itself, by itself, is overpowered. Don't apply it to a purportedly weak class and compare that as applied to a strong class.
I am comparing two combatant feats. That is apples and apples. Just like when you talked about Weapon Specialization in your post.
If INA is allowed for Unarmed Strikes, only Monks (out of core classes) can get it. Hence, it has to be compared with Monks. Since it is a combat related feat, comparing it to another combat related feat (like Power Attack) is reasonable.
Balance discussions need to address the game system as whole, not some artificial "you cannot compare a weak class with a strong class". The entire point of the balance discussion in this case is that only the weak class can get this feat (if at all) and that weak class can do less damage with this feat than other combatant classes will do with Power Attack, then it is not unbalancing.

This analysis is completely irrelevant from my comment.
Nonsense.
Power Attack can be used with any melee attack and any melee weapon. INA cannot.
Power Attack can be used by any class. INA (assuming it can be used with Unarmed Strike as per the balance comparison) can only be used by Monks.
Power Attack can be adjusted to do varying amounts of extra damage. INA cannot.
Power Attack can be taken at first level by some classes and third level for a Monk. INA cannot be taken until sixth level for a Monk.
Power Attack can do a lot more damage such as "near sure hit" situations (e.g. opponent helpless). INA cannot.
INA does not take a minus to the "to hit" rolls. Power Attack does.
There are a lot more Pros on the Power Attack side than on the INA side.
This is a case of you being unable to accept the fact that balance wise, INA is comparable to another feat called Power Attack. Once I illustrated that, the balance part of the damage part of the discussion is what is irrelevant. You did not post significant counter reasoning that INA is more powerful or has more utility than Power Attack, you just were unable to accept that the analysis illustrates your balance point irrelevant.
You want a different more "apples to apples" comparison. Fine.
Monk with INA versus Monk with Magical Weapon. Does the addition of the feat greatly increase the amount of damage the Monk can do over what the Monk can ALREADY do using core rules?
Monk with INA cannot use it for a Magical Monk Weapon. Hence, he loses the damage for Holy or Bane and special abilities such as Vorpal or Wounding at 20th level in order to gain +7 points of damage with an Unarmed Strike. This does not sound especially unbalanced.
Plus, in order to have the same to hit as with a magical weapon, a Monk needs to have an Amulet of Mighty Fists (unless he has a Druid friend). How does damage work out at these various levels of INA plus Amulet versus Magical Weapon assuming 25% of wealth by level for this (and remember, the Magical Weapon side does not require a feat, hence, it SHOULD average less damage):
6 2D6 (cannot yet afford amulet) vs D6 +1 (+1 kama), 2.5 damage less, but +1 to hit
8 2D8 + 1 (+1 amulet) vs D6 +1 (+1 kama cannot yet afford better), 4.5 damage less
12 3D6 + 1 (+1 amulet cannot yet afford +2) vs D6 + 1 + 2D6 (+1 Holy kama), same
16 3D8 + 3 (+3 amulet) vs D6 + 3 + 2D6 (+3 Holy kama), 3 damage less
20 4D8 + 5 (+5 amulet) vs D6 + 5 + 2D6 + ~10 (+5 Holy Wounding kama), 1.5 damage more
Granted, Holy and Wounding do not work against all opponents, but they work against the vast majority of them. And even when they do not work, the Monk could always fall back on his normal Unarmed Strike attacks to do more damage. You'll also note that the Amulet cost more than the Kama at every level except level 8.
All in all, this is not a real lot more damage like Frank and you indicated. We are talking about a range of -1.5 to +4.5 (level and items depending) damage with regard to what the Monk can already typically do WITHOUT taking the INA feat.
This is not as unbalanced as you claim. In fact, it is white noise for the most part compared to what the Monk can already do with a magical weapon and without a feat. And, it is definitely white noise compared to what other combatant classes can do.
The damage balance part of this discussion is mostly a red herring and irrelevant.
