For outgoing connections, that's what we do in IPv4, and it has the same
disadvantages. I'd say the most important are: a) it breaks protocols that
encode the IP address in the stream and requires those protocols to
implement NAT traversal, and b) it requires periodic keepalives to keep the
mapping alive.
