Your View on DPI

[ninurta2005-/E1597aS9LQAvxtiuMwx3w at public.gmane.org (ninurta2005)]

The U.S. Federal Governments potential use of Einstein 3 which includes deep 
packet inspection, would certainly qualify
as a example. http://epic.org/privacy/dpi/

Hi,

While I share the general view that Deep Packet Inspection (DPI)
is unfair in some regards, it may have legitimate use in Traffic Management,
Routing etc. 

I can't help but believe that Big Brother (National Security Agency)
has a lot of people dedicated to DPI, like it or not ...
