For one host with multiple, globally-unqiue addresses to talk  
optimally to another similarly-equipped host, such that failures in  
reachability of individual addresses should not cause sessions to  
fail, both hosts would need to be shim6-capable.

Which is not to say that there is no value in a non-ubiquitous  
deployment -- rather, the value will grow as deployment proceeds.
