It would be interesting to map all the different models that are being implemented/proposed for TTN. I would guess that all these models are bringing some value to their respective communities. As mentioned previously we are very interested in creating cooperative infrastructure. We have had discussions about engaging local libraries that a centres of public learning can install/host a gateway and community workshops take place within those libraries to enable people to understand and exploit the technology.
The difficulty with this is that libraries don't have the capacity to do this - so this would be very much a Things community endeavour. We are also looking at whether this approach could work in schools as well.
