A few years ago my boss was at a remote sensing meeting where the Chinese
participants casually dropped some extremely high-res. satellite images of San
Francisco on the table.  The guys from the US Gov't turned white, so they 
clearly hadn't known of this capability. 

Now we have http://eprint.iacr.org/2004/

    Collisions for Hash Functions MD4, MD5, HAVAL-128 and RIPEMD 
    Xiaoyun Wang and Dengguo Feng and Xuejia Lai and Hongbo Yu 

This seems to prove what has been suspected, MD5 is not a collision resistant
as Rivest had hoped.  It would be interesting to know how many NSA types
needed oxygen after that paper was presented.
