The charter has significantly changed these days and I would like to 
re-state the need for 
seamless interfacing between 6lowapp and the DPWS world. DPWS is a low 
cost SOA solution at 
device level and will play a major role in future Building and Industrial 
Automation systems 
(embedded in zone controllers, Automation servers, industrial PLCs...). 
Besides, in some 
cases, native support of DPWS in VISTA and Windows 7 network explorer 
might help in simplifying
discovery and commissioning of devices.
The HTTP REST model proposed in the new charter is sufficient for simple 
get/set operations but
I join Vlad Trifa when saying that there are requirements for more than 
just request/response 
messaging patterns like e.g. publish/subscribe (multicast). IMO seamless 
interfacing with WS_* 
(at least straightforward proxying) must be provided to ensure efficient 
integration of 6lowpan networks
in upcoming architectures.

Regards.
