If you want really strong encryption, IP-level encryption is not
enough, you need "line-encryptioin" (not sure about the correct
English term - this is when data is encrypted at low level, so it
appears as a constant stream of noise without variation is the rate).
But "line-encryption" is obviusly works against batery time of live
and is unlikely to be deployed in commercial networks.
