Because those towers, nodes need to be connected to something to be  
useful and what we use to do this today is fibre.

Here is an article that reckons that we could get 10Gb out of our  
current copper.  Written in 2006 it doesn't seem to have eventuated.

Note that the potential bandwidth of fibre is much, much greater than  
this.  I think people have got 69Tb (Terrabits) out of a single fibre  
240Km long.  I expect that we will be able to get several orders of  
magnitude better than that in the future.

We still have some microwave links although I expect they are dying  
out .... because of fibre.

I've used i-burst and it's fun but it's not serious broadband.   
Perhaps it might qualify as "Australian broadband" but seriously, we  
need to do better.

Not sure where you're going with that.  You can use radio while  
driving but TV?  Dangerous!  TV as such has simply not ever been as  
flexible as radio.  Not until youtube and broadband.  Not until 4G and
