New submission from Dan Forsberg <[email-masked]>:

Devices that have multiple interfaces can have multiple
network connections (with different IP addresses) on at the
same time. On the IP level the access network may still be
the same..

You are talking about room for possible optimizations, not
problems. I suggest we open this as a new issue, and follow
it up from there. Rather than continuously optimizing the
basic design. I think such optimizations touch more than the
PANA design, so we should do a more thorough analysis.
