Martin,
I like your idea for the commit protocol in that it resolves the
vandalous address substitution attack. However, I don't see a way to
prevent privacy loss without adverse impact to the scenario.
Anyone could perform the handshake and thereby obtain the payment
request. Therefore to
BIP70 is a protocol for getting a user's wallet client communicate with a
merchant's server in order to agree on details like where to send the
payment, how much to send, what the shipping address is, sending a receipt
back, and much more using various extensions that adds more functionality.
Why would anyone want to do anything about payment before choosing
what he wants to buy and for what price? I've never used Amazon but
isn't filling a form with shipping information enough?

That's not what this is
Let's say you're visiting an international webshop. But they don't ship to
your country. Wouldn't you want to know that before your start filling the
cart? With this, your wallet / browser extension could tell you right away
that you can't shop there. No time wasted!
Why my wallet has to

I still don't understand. The website can have this information
available. This is exactly what e-bay does - it displays shipping
information to my country before I do anything. What's the problem?
Also with other stuff, website can do it and browser extension can do
it too without messing with

We can certainly imagine many BIP70 extensions, but for things like
auto-filling shipping addresses, is the wallet the best place to do it? My
browser already knows how to fill out this data in credit card forms, it
would make sense to reuse that for Bitcoin.
It sounds like you want a kind of
