Hi Stil, Karl, Tom and other linkers...

The 20% figure I quoted on the podcast was a flipant one - as you may well

Mostly this is based on a couple of factors:
 - Most organisations don't know what traffic is important.
   These organisations tend to not encrypt anything on the wire.
 - Of the organisations that do understand what is important,
   many value the transient information as less than the cost of encryption
 - of those that can justify the encryption, many have incomplete coverage.

My experience outside of those environments with Legislative requirement or
classification requirement is that VERY FEW actually encrypt any data(Note
1) in motion across thier internal

In my particular case, I am fortunate enough to say that data travelling
across networks where I do not control the routing tables is encrypted over
20% of the time (depending on the link and the traffic). We also encrypt a
pile of our email and are working on a much deeper implementation of
encryption of datra both at rest and in motion throughout the organisation.

(Note 1: Except authentication information - because Microsoft finally got
it right, and encrypts it for them by default)
