Not quite -- the practical usefulness of the multi-homing increases  
with the deployment of shim6-capable stacks. You could imagine a  
threshold of server and host upgrades which would provide useful  
multi-homing a good proportion of the time without universal deployment.

If Linux and the currently-supported variants of Windows were to be  
updated to support shim6, and we waited through three or four widely- 
publicised security vulnerabilities which required OS/kernel  
upgrades, perhaps that would be sufficient deployment for the  
benefits of shim6 to be felt, most of the time. My hands are waving  
again, of course.

I feel fairly certain I have exceeded some kind of unenforced posting  
threshold to this list in the last twelve hours. I will try hard to  
be quiet for a while, now :-)
