I just checked the Cryptography Today FAQ from rsa.com and found 
precious little clues in the section about RC2 and RC4, except for the 

  "RC2 and RC4 are proprietary algorithms of RSA Data Security, Inc.; 
   details have not been published" (sic)

They claim that RC4 is 10 or more times as fast as DES.  Has anyone done 
any speed trials against libdes yet?
