I knew when I started that different housing layouts would require different topologies. What I hadn't counted on was the sheer number of parameters that factor into the decision. It's not like you can just say that you want to run fiber to the home. Will that be PON or end-run? Will the deployment be arial or underground? Even if you narrow that one down you're faced with what type of underground deployment (direct-bury or in conduit, etc). Then you get into questions about what kind of fiber... The list of decisions goes on and on. Luckily I'm getting very good advice from people who want to see more fiber rollouts.
All this leaves me in a bit of a chicken/egg situation. I can't convince people to sign up for the network until I know how much it's going to cost and where it will run. However, I can't easily make many of these decisions regarding the network until I have a feel for their level of interest either (and if they'll let me dig in their yards). It's tough to show up at someone's door and ask them if they're interested if you can't give them details. That's probably exactly what I'm going to have to do though.
