Yes.  Having run into what appeared to be a dead end on the encrypted 
filesystem angle, I was trying alternate approaches.

The advantage of (en|de)crypting a filesystem like that is I can walk up to 
any Linux box and use it.

The disadvantage is that I have to perform those two operations, plus 
writing /dev/random over the unencrypted version then deleting it.  A bit of 
a hassle.

I can't imagine there are ANY encrypted filesystems that work with both 
Windows and Linux.  I didn't find any, anyway.

The thumbdrive came with some folder crypting stuff.  I should try running 
that in wine and see what happens.  That would be interesting.
