> 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.
