No, the point is to take say, a CDROM which you have preloaded with pure
random data, i.e. burncd /dev/random, then you create a proper sized
partition, then using gxor you meld the two...

Then for any read/write requests, you take the data, read from the OTP,
xor the data, and pass it on...  Then when you go away, you take the
cdrom, w/o it, there is no data...

I like the idea, and it would be a perfect project from someone who is
learning geom...
