JP> Yes I agree, although the scope may be a bit wide - that being said, since we started the document, terms such such Internet of Things
have been widely adopted and will help referring to a set of technologies, as opposed to a specific WG. By the way, you are right that these
terms are now use beyond the ROLL WG.

by Working Groups specifying solutions for the Internet of Things"

Many Thanks for your comments.
