My understanding of this difference is that in our current
proposal, the peers can register their alternative addresses
and failover to the other addresses if there's a connectivity
problem in the currently used address. (I don't think you
can do this in basic IKEv2, and personally, I think its a good
tradeoff in terms of functionality vs. effort and configuration.)
This is what I call the "failover" multihoming model.

In the SCTP multihoming model we can choose more independently
where to send data, even if there's still the concept of a
primary (default) path.

In the load balancing multihoming model we can send even
the same stream over multiple paths, and still perform appropriate
load balancing, congestion avoidance, and acknowledgement
tasks.
