Untraceable messaging

Today on Slashdot there was a story about a messaging service called VaporStream that allows for completely recordless digital communication. They say “messages cannot be forwarded, edited, printed or saved.” See, I don’t buy into stories like that. Obviously, the message must be displayed at some point. What is keeping me from taking a digital camera and taking a picture of the screen. Then I have a record of what was sent. Maybe legally it is recordless, but I think it is important to remember there is always ways to take a camera or a tape recorder to things that weren’t meant to be recorded.
