Thanks for looking at this.

Just to confirm... after your server does SO_BINDTODEVICE to 'lo', your
clients on the same host can make a successful connection to global IPv6
addresses which are assigned to the *other* interfaces? 

Can you show your version of the test app, and your results? What kernel
is this on?
