the draft also refers to a previous draft of August/2005 (SP 800-
57)
which publishes a table of comparable strengths:
http://csrc.nist.gov/publications/nistpubs/800-57/SP800-57-
Part1.pdf
p.63

note that 3-DES is now referred to as TDEA
should this perhaps be included in rfc 2440 when 3-DES is 
mentioned?
i.e.
when 3-DES is first mentioned, 
it should be referred to as 3-DES(also known as TDEA)
