Actually, if there are no well-known ports then there must presumably be
some mechanism to discover what dynamic port the app is using. 

Why stop at ports then? The same mechanism can be used to discover what
IP address that app is using. 
With end-to-end discovery, who needs static IP(v6) addresses?
