We would need a semi-B4RN, in that case, using copper unless BT could be persuaded to finish the job off properly and get rid of the remaining ~ 500 - 1000 m from an FTTC cab to the unluckiest householder. I suppose there's nothing stopping you from going the whole hog (FTTP) later is there? Apart from doubling up of installation effort, first fibre-copper interfacing, then FTTP all the way.
I had never given any thought to the possibility of a community backed FTTx cab. I had though about FTTRN and so on. I wonder if in a few years time this might be a way of getting the stupid USO done, whatever if anything it turns out to mean in 2020.
If BT were to site a cab in the township, would someone need to donate some electricity to them?
