That's what it says here:
     http://www.entropykey.co.uk/tech/

It certainly needs an encryption key on the userspace daemon bit, which 
unless the person coding is very silly, usually implies that the PC is 
defended against impersonation

It seems way overkill for what I wanted, but the end result is that it 
does seem to be a very well thought out device, even more so considering 
all the other hardware devices I found through google are in the 400 
euro area (and at least two I looked at were thunking great big 
bricks...).  This thing is well inside my toy buying threshold...
