Yes, there needs to be some up-front investment to proactively deploy these
boxes/taps in strategic places. I did some analysis and the numbers are 
doable even
for the largest networks.

But then we get into philosophy; I have a lot of screwdrivers at home 
laying around but
I would much rather invest in chisels rather than keep trying carving wood 
with flathead
screwdrivers (but that's just me..)
