> When a new new node (version N) contacts an old node (version N-1) for the first time, the old node will not understand the message.  One resolution mechanism would be for the old node to "bounce" the message back to the sender.  The sender would then respond by translating the message to the appropriate version and resending it.
> For this to work, 0.7.1 will need to have the "bounce" feature.
