Yes, it does appear to be what I need:

       -L localident
              specifies  (for  multi-homed  machines)  that  they
              should use specified identity  when  connecting  to
              the  destination.  Think of server with multiple IP
              numbers due to virtual hosting,  for  example.   At
              such  systems  there  may be situation when virtual
              identity needs to be used for reaching the destina-
              tion system.

              Understood formats for local identity are:

              - "iface:eth0" -- (eth0 device in the system)
              - "[ipv6.1111:2222:3333:...]" -- Literal IPv6 address for IPv6 system
              - "[1.2.3.4]" -- Literal IPv4 address for non-IPv6 system
              - "some.host.name" -- DNS/hosts data registered name

Yes, that is right.  The part I'm still not sure about is whether
tearing down the interface will immediately kill the outgoing
transport agents.
