And neither do 6in4 tunnels, like HE offer, if they are initiated
from the same points in the network.

Now if people wrote their applications with multi-homed support
that didn't suck, broken 6to4 tunnels wouldn't be a major issue.
You don't have to wait 30 seconds to try the next address.  You can
try more than one address.  This could be multiple IPv4 addresses,
multiple IPv6 address or a mix of IPv4 and IPv6 addresses.
