To follow up on a post last year where I suggested that Rabin's information dispersal scheme might be useful for sending large files across unreliable remailer networks, I built a shareware package called Disperse/Collect out of my own Crypto++ library. Disperse splits up files into redundant pieces and encodes them in base 64. Collect decodes them and reconstructs the original files.
