Re: Wassenaar summary (and a funny new loophole)



Unfortunately, since Wassenaar is not the law, only an agreement
by bureaucrats to make laws or regulations sort of like it if
they can talk their pet legislatures into rubberstamping them,
this doesn't help.  

You can't take a bureaucrat to court and 
insist that she rescind a regulation that was stronger than the 
Minimum Daily Repression specified in the "Arrangement" -
you can only insist on whatever your nation's constitution (if any)
or fundamental rights document (if any) specifies, 
or perhaps go to the World Court or some European Union or 
European Community court and argue the case there.
But most of these rights documents say things like
"except for national security" and aren't very enforceable
even if they do plainly state that your rights are stronger than that.

I assume you mean 3DESDecrypt(backwards(k),x) ?  It still doesn't work,
because 3DESEncrypt is still symmetric with 3DESDecrypt,
and SED3Decrypt is still symmetric with 3DESEncrypt(backwards(k),x).
But you could still come up with something that meets the
letter of the non-law, just for the fun of tweaking them.

I think it's more realistic to go for the various
General Software Exemptions and Public Domain Exemptions,
and generally lobby legislatures to slow down on implementing Bad Things,
and let them see there's money to be made for their countries' 
local businesses by not cooperating.  

A potentially valuable change to go for would be to allow 
export between members of the Wassenaar, or the EC, or whatever.
After all, the whole purpose of the COCOM that Wassenaar grew out of
was to keep Commies from getting militarily valuable technology,
and now that there aren't any Commies (unless you count the Chinese or Cubans)
and they've let the Russians into Wassenaar, the whole thing's
prima facie stupid anyway.
