So is it a National Network or network components that those who want a 
National Network have to put together with components from other suppliers?

I don't have a problem with NBN not building a replacement long-haul 
fibre network. What I do have a problem with is them calling it a 
National Network if it isn't.

Why doesn't NBN Co buy services from whomever and put together a single 
National Network? Then it really would be a national infrastructure project.
