TCP and UDP ports allow for multiple communication channels to exist
between two IP addresses.  Likewise, SMB FileIDs allow for multiple
communication channels to exist between two endpoints.  I think the
reason it sounds weird is because the conversation stuff is defined in
terms of addresses and ports, instead of more generic multiplexing
terms.  If you think of it in multiplexing terms, it makes perfect
sense.  To me, at least. :)
