for the appropriately paranoid

I would say that most accompaniers don't do most of the things in this guide to secure communications by the great folks at DigiActive, but given the recent DAS scandal in Colombia, it seems worth upping the hassle factor. What a pain. Also worth noting that they say cellphones should be left outside of sensitive meetings in the US too, since the ability to listen through them is commercially available and works on US networks too. I would assume that means Canada too.
