In 3rd edition the answer was definately
yes. No questions asked, natural weapons were a subset of unarmed attacks and thus you could flying kick with all of your pounce attacks together.
In 3.5 the answer is a lot muddier - as Natural Weapons are sometimes listed as a form of Unarmed Attack, and sometimes Unarmed Attacks are listed as a form of Natural Weapon. The dependency - and thus the applicability of the feat - is completely up in the air.
It all comes down to how unarmed rules apply to natural weapons - and that has contradictory answers in the 3.5 rulebook. It also has contradictory answers coming out of custserv and the Sage.
As to whether this is balanced - that depends upon oyur game. Certainly you can do similar things as a Cavalier with Spirited Charge and Full Mounted Attack, or as a Singh Ranger - or as a Druid who casts Lion's Pounce on his friends (or himself). If you for some reason thought that
any of those were unbalanced - you'd have to nerf all of them as the effects aren't even particularly different.

IMC, I would certainly rule that, regardless of Pounce effects, Cleave effects, or the like, only the first attack ever receives Charge-dependent bonuses.
There is no support, at all, for this "ruling". So much so that this isn't even a ruling - it's a house rule nerf of the charge bonuses. I've seen charge-fighters in action - I've
played charge-fighters. It's nasty - but taking Cleave away from them nerfs them into uselessness.
Fighters need Cleave to live. It's not a "realistic" feat - but as long as Wizards keep being able to cast the same spells on more enemies with better save DCs - Fighters need to have their Cleave Attacks. Really.
