They have a whole bunch of companies like http://secured3d.com/%20and%20fabsecure.com. and Fabsecure.com
We had a test unit a while ago, but it didn't work all that well and had quite a few security issues (then again, it was a early beta). I do see that they've got some financial backing now, so maybe it improved a lot. At the time the device was like 500 ish euro, which is way to expensive imho.
