Some of this is probably obvious, but anyway..
BIA: "IPv4 application on IPv6 node can talk to an IPv6 application on
another IPv6 node"
DSTM: "IPv4 application on IPv4/v6 node can talk to an IPv4 application on
IPv4(/v6) nodes" (in addition to full IPv6 connectivity).
So, if the destination site does not have all the services IPv6-enabled,
BIA won't help (at least completely) and DSTM is rather useful if one
wants to avoid protocol translation.
