Don't we first we need to have an actual network to plan long term for? 
Planning 3 years down the track is a bit pointless with the rate 
technology is advancing, something better will probably be out by then 
that solves all our problems in a little box (like the proprietary nokia 
rooftop router but non-proprietary) you can make/buy for $100.

Wait, why is the couple directional and an omni idea bad? Even if 
density gets so high that internal cards will work to link to the next 
hop, to alleviate bandwidth woes in a heavy traffic area, you could 
shoot a 5km link out of it rather than go through every single hop on 
the way out. I think this is a far better plan to solve the bandwidth 
problems than things like capping/throttling/mojo, because once you 
start doing things like that, you start turning into telstra.
