BTCmsg Protocol v1 (2011-09-18)
===============================

Each message is represented by multiple payment which is calculated by
the following algorithm:
1. Two first chars for message type ('01' for md5, '02' for ascii).
2. Then the message in hex (python binascii.hexlify).
3. Split the long string to groups of 4 hex digits.
4. Each group of 4 hex (e.g. 2 ascii letters from the message) is 
   represented by a payment in satoshi (maximum 0xffff=65535).

With Bitcoin 0.7 it's possible to keep your private keys
entirely offline without third party software.

In this example we have two hosts [offline] which is
totally offline and without a copy of the blockchain
and [online] which is a regular online node, both
running bitcoin 0.7.

2-of-2 escrow example

Carbide81 wants to pay carbide80 50tnbtc but prevent carebide80 from cheating him.

First each party creates a new address, and then shares them. Then uses the 
resulting addresses to make a p2sh address (begins with '3' for bitcoin,
'2' for testnet) that requires both parties to sign to release:
