There are many a model that can be used for this. I have an idea as well, but at the end of the day, time isn't something I have.
fortunately I have tons of time, but what I've also noticed is that people are quite eager to commit effort and resources once they see my "vision".
surprisingly the ISP was the first to be onboard
I haven't done the nitty gritty details as yet, but the broad outline is as follows, find 50 people to contract to a 24 month contract at R2000 initial set cost and R350pm
This will cover the cost of a 100mbps 10:1 line which then needs to be distributed to these people. The trick is obviously reliable distribution. A surplus of around R5000pm will be created which can then be pumped back into the area via CCTV cameras or better internet or whatever benefits the users as a group.
