Something which only XORed data would prolly be ok (I'm not a lawyer)
but it can be decrypted in very short order by someone with access to
the specials tools used to decrypt that sort of thing.  XOR requires
only pencil and paper, and a hex calculator and a C compiler help.  :)
In other words, XOR is not secure enough to consider a threat by
most people.

So do we all.  There is no real clear definition, no matter what the
State Department claims.  This whole area is hard to deal with.
