We've been using truecrypt for quite a while now. The tool is great, does what it's supposed to and best of all it's free. One of the best functions is the ability to escrow the keys for data retrieval later -- policy demands we have this. I especially enjoy the traveler's disk --we're using this for our USB keys. Can't wait to watch the vid because we wrote several docs for people to use the utility so maybe linking to your video would complement them.
