Hi Christian:
Thanks for bringing up the charter discussion. My comments are in-line.

Based on received feedback, I have a new suggestion for charter scope.
--- start of scope ---
Scope of 6lowpan:
Produce "Optimization of the Adhoc Routing Protocol for 6lowpans"
to apply an existing MANET Protocol to LoWPANs.
Agree.
Produce "Optimization of the Neighbor Discovery Protocol for 6lowpans"
to define how to apply the existing Neighbor Discovery protocol in a
6lowpan.
Agree.
Produce "IPv6 over Low Power WPAN Security Analysis" to define the
assumptions for a security model for 6lowpan. This includes analysis
of threats, identify types of devices and define the levels of trust
between these devices.
I think this document would be an informational document. In addition to analysis of threats, it would be useful to discuss what level of security to be applied in
different level of communications such as in application-layer, network layer or link-layer.
Produce "6lowpan Co-existence with other Networks" to define how to
co-exist with other networks. This includes analysis of how to survive
interference caused by IEEE 802.11 based networks, and investigate how
to recognize and co-exist with other networks based on IEEE 802.15.4.
This might be another useful guideline to the community. But I'd think, it as a
low priority item.
As such, the working group may also work on informational documents for
service discovery, scalability of 6lowpan (routing and addressing),
I am not sure about importance of scalability in 6lowPan. I thought, we introduced
IPv6 to solve the scalability problem. If we use 64bit UID address scheme for
MAC address, then I don't see a scalability issue.
The 16bit MAC addresses could be treated as local addresses - same way as
IPv6 treats link-local addresses - we can simply decide not to route those
addresses outside local PAN and use 64bit unique address for global communication end-to-end. Adding 16bit address support for inter-pan communication will add much complexity.

mobility issues, naming service for mesh layer and gateway architecture.
The working group will reuse existing specifications whenever
reasonable and possible.
The working group will also serve as a venue for ongoing discussions
on other topics related to the more complete list outlined above.
Additional related milestones may be added in the future via a
rechartering operation.
Note: As may be obvious from its official name above, this particular
working group will not work on IPv4 over IEEE 802.15.4 specifications.
Given the limitations of the target devices, dual-stack deployments
are not practical. Because of its higher potential for header
compression, its support for the huge number of devices expected and
of cleanly built-in features such as address autoconfiguration, IPv6
is the exclusive focus of the working group.

Please provide feedback.

Subject: Re: [6lowpan] new 6lowpan charter
new 6lowpan charterI believe 6lowpan adhoc routing protocol must be
included into our rechartering more specific than
now. It is one of urgent task toward 6LoWPAN
Current text is just copy-and-paste from the
existing charter as follows:
"As such, the working group may also work on an
informational document to show how to apply an
existing MANET protocol to LoWPANs ( e.g.,
AODV, OLSR, DYMO, etc)."
So, my suggestion is as follows:
Produce "Optimization of the Adhoc Routing Protocol
for 6lowpans" to apply an existing MANET Protocol
to LoWPANs.
Thanks in advance.

Hi.
During the 6lowpan interim meeting in January, the working group
discussed possible topics for a future rechartering of 6lowpan. Based on
available information from that meeting I've compiled the following
text, which is an edited version of the scope present in the current
6lowpan charter. Feedback is appreciated.
--- start of scope ---
Scope of 6lowpan:
Produce "Optimization of the Neighbor Discovery Protocol for 6lowpans"
to define how to apply the existing Neighbor Discovery protocol in a
6lowpan.
Produce "IPv6 over Low Power WPAN Security Analysis" to define the
assumptions for a security model for 6lowpan. This includes analysis
of threats, identify types of devices and define the levels of trust
between these devices.
Produce "6lowpan Co-existence with other Networks" to define how to
co-exist with other networks. This includes analysis of how to survive
interference caused by IEEE 802.11 based networks, and investigate how
to
recognize and co-exist with other networks based on IEEE 802.15.4 .
As such, the working group may also work on an informational document
to show how to apply an existing MANET protocol to LoWPANs (e.g.,
AODV, OLSR, DYMO, etc).
The working group will reuse existing specifications whenever
