   And then there is CDMF, which is rather similar to DES, and which
   enjoys similar exportability as RC2/RC4 (except the review time
   is 15 days instead of 7)... 

IP issues aside, what's the strength of CDMF?  My understanding of 40
bit RC4 is that it doesn't give away anything about the NSA's ability to
crack cyphers.  40-bit RC4 is reportedly quiet easy for anyone to
cryptoanalyze.  If CDMF is similarily weak, what's the point of using it
at all?
