That's a very good point. In case of p2p agents we will only be sending
messages using a standard send function. So, there is no way to tell the
message type. We should add an int32 for message type considering that we
have a standard number of messages.
If int32 messageType == 1 then that could an authentication message and so
on. What do you say?
