So I RTFA and I have several salient points to make. Firstly... uh. Um. Well it seems I've kinda forgotten what it's about, now that I think about it...

Interesting summary but for some strange reason after I finished reading it I felt like I had just finished watching an Enzyte commercial...

To everyone saying 'if someone has physical access you're hosed anyway'... that simply isn't true. If you have a laptop and encrypt your data correctly, it was thought that it was mathematically infeasible to recover the data if your laptop was stolen. But with this (new?) technique, if it works well enough to be reliable, you could still be fucked even if you took the precaution of encrypting everything.
