Another approach is to look at the underlying motivation for these
approaches, i.e., addressing deployment and usage hurdles:

* reducing initial capital expenditures (for the network and the end user,
or both)
* providing additional sources of capital (beyond the traditional
carrier-based financing)
* reducing on-going operational costs (such as backhaul or network
administration)
* leveraging expertise
* reducing hurdles to adoption (digital literacy; literacy, in general;
relevance, etc.)

Most of the examples given, except the testbed, seem to fall into one or
more of these categories. Given that there are likely more solutions than
the examples discussed, it might be helpful to focus on the goals, as that
then also allows to evaluate whether and to what extent a solution meets
the goal. Otherwise, it's just technology for coolness' sake.
