A community in Lancashire, England, has taken it upon themselves to dig, lay and build a complete 1 Gbps FTTH network. Members of the community have been able to buy shares to finance the project, and then they've mucked in to carry out all the leg-work themselves, with farmers digging trenches and other locals installing the technology. I find it very inspiring: especially given I live in London and still can't get FTTH. Business plan, videos and info on their website: http://b4rn.org.uk
