   Here in NZ, the fibre terminates in a separate box called the ?ONT?.   
   Everything up to and including that box is the responsibility of a   
   company called ?Tuatahi Fibre?, which is *not* an ISP (and is not   
   allowed to become one). Basically they provide a layer-2 connection   
   between my house and the routers/switches/whatever for the service   
   providers, and their job is to treat all service providers equally.   
      
   Also, that box is to be considered part of the fittings of the house,   
   so it stays with the house, and doesn?t move if/when the residents   
   move house. The installation of the box (and the physical fibre   
   connection to it) was done free of charge, under a Government-funded   
   plan.   
      
   The particular ONT box in my house has 4 Ethernet ports and 2   
   telephone landline ports. These can be independently assigned to   
   different services, coming from different providers. E.g. the one   
   that?s live for my ISP connection has an Ethernet cable running   
   between it and my actual router, which I bought from a local store.

   Hmmm ... I?m thinking it might be possible to isolate that box on a   
   dedicated Ethernet port on a Linux box, so you could use a packet   
   filter to block anything DHCP-related, and only let through the stuff   
   you want ...
