A pub/priv crypto engine on a USB key is about the only secure way to do it.
Anything else will be hacked in a week, not to say the USB key won't be hacked,
it will just slow things down a bit. A famous example of how to do *real*
security is autocad $version (I can't recall the number) which was rather evil,
and did a basic check via a dongle. This check was easy to avoid, and the fix
for that was out inside a week. The initial hack didn't notice there was a
second check against the dongle which slightly touched the files as they were
saved, so your angles drifted slightly every time you saved/loaded. What you
might consider if you're editing data is crypto it to the disk with a pub key,
then let the dongle uncrypto it on read.
