But I can't field deploy this 2 continents away at 4am with 10 mins
notice...


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..)

Livio.
