using MH is not a magic "re-use"

Alex,

Static configuration of prefixes is only one way. Routing
protocols,
Prefix Delegation and other mechanisms are also possible, in
which case
the HA does not have prior knowledge of such things.

In any case, what is it that you are proposing exactly?

(Routing protocols do not distribute in any way prefixes to
be
assigned, while DHCP does.)

How do you see DHCP assign addresses and flow preferences to
LFN such
that MR is authorized to do flow bindings for LFN's IP
address?  MR
snooping the DHCP allocation?  MR allocating to LFN?  These
are
unknowns.  HEsham seemed to say out of scope - but without
it flow
bindings on MR about LFN's IP address are not possible.

> In any case, what is it that you are proposing exactly?

Without a proper mechanism for LFN to delegate authorization
to MR
about its preferences MR has no possibility to do flow
bindings for an
LFN - in which case one can't say that flow bindings are for
MR,
they're only for MH, no NEMO.

I don't think I'm proposing any other thing than keep flow
bindings in
the context of MH only, not for MR.

I certainly don't want the MR to make a decision on its own
about
which apps on which interfaces to use, when those apps run
on LFNs.
Its LFN who's in charge of its apps.

Alex
