In the future we will hopefully have confidential transactions as proposed by gmaxwell and then it will not be possible to know what amount of BTC is being moved around, also we will have coinjoin and other privacy stuff. Wouldn't this make your format incompatible with those transactions? or you can still get the information needed?

Also I think in the future we will have some sort of "email" format where you can give to people and when they send you coins it automatically receives them in newly generated addresses for better privacy easily instead of the complex long addresses. I think Bitcoin should have this "email of money" instead of trying to look like an annoying bank account (I hate when I have to share bank account details because the numbers are so long and one mistake and you are fucked)
