Agreed. This is definitely a limitation that needs to be addressed. However, the administrative model for it needs some work -- e.g., you'd really want to be able to specify targets on a per-IPMP-group basis, not globally. I'd envisioned we could do this in the future via an "ipmp-targets" IP property that could be set on each ipmp IP interface via ipadm(1M) (in a manner analogous to dladm(1M) link properties) -- but as we don't even have ipadm yet, being able to do it that way is admittedly a ways off. -- meem
