I think what was meant is a logical client. For example, it should be possible
to distinguish two logical connections (two pairs of TCP/IP connections) from
the same IP. This is necessary to handle clients connecting from behind a NAT,
at least.

If this is the requirement, have the client include the same random cookie in
both TCP connections, or, have one connection refer to the client IP *and* port
of the other.
