Great foresight! You invented the payment protocol!

Hello,

If I fully understand the need for anonymous transaction, there's *a lot* of cases when you do want to be authentified and to send a message with your transaction. With bitcoin, I imagine a system like the following:

There's also a need for a bank account ID that you can easily remember.

Let's say that my bitcoin bank is  ploum.net. My id could be ploum.net/ploum

If my friend "Joe" (which has an account on bitcoin.com)  want to pay me 5BTC for a party, in his banking software, he just put :

Receiver : http://ploum.net/ploum
Amount : 5
Message : thanks for the party buddy


What will happen then is the following :

Bitcoin.com                                               http://ploum.net/ploum
-------------                                               -----------

New transaction
From Joe Pal ( http://bitcoin.com/joe )
Message : Thanks for the party buddy
                                                      -------->
                                                                Replying with new bitcoin adress
                                                                15SCCTDK9xcZyKFWXsPRXYS9s1m3Mikcxs
                                                     <---------
Using the bitcoin adress to pay 5BTC

                                                   

This makes it at least as useful as the current banking system. Even more because account number are now a simple URL.


Advantages:
-------------
+ Easy to use, easy to give your account ID to someone.
+ Hide completely the ugly bitcoin adress from end user sight.
+ Allow to transmit message
+ Could also be used anonymously (for example, by going with a web browser to http://ploum.net/ploum, you can receive a bitcoin adress that you can use manually)
+ Decentralized. Anyone with a http server can implement his own bitcoin bank compatible with the system.

Disadvantages:
----------------
- No real authentification (anybody can fake Joe Pal and pay for him. But does it make sense to forbid that ?)
- Someone using the bitcoin adress manually could use it multiple times and you will always see the same message. But the client might display only the total received by a bitcoin adress, not each transaction.



Question :
-----------

Is there already discussions about doing that ?

Is there any standardization on the communication between ploum.net and bitcoin.com ?

Did I missed something ?
