Besides the question of which WG this might fall under is the question
of how any of the work groups are going to engage with the project
communities. There is a group of developers pushing forward on cellsv2
in Nova there should be some level of engagement between them and
whomever is discussing the fog/edge computing use case. To me it seems
like there's some level of overlap between the efforts even if cellsv2
is not a full solution. But whatever conversations are taking place
about fog/edge or large scale distributed use cases seem  to be
happening in channels that I am not aware of, and I haven't heard any
other cells developers mention them either.

So let's please find a way for people who are interested in these use
cases to talk to the developers who are working on similar things.
