There is still a void in the arena of free public encryption systems for regular human beings. It would be wonderful if somebody would put a reasonably secure package (much like PGP) and copyleft the source. PGP has never been a very useful tool to me as a programmer because of its internal structure. What I'd need, if I wanted to integrate this technology into new platforms such as voice communication or an encrypted file system, is a library of tools for shuffling this data around and piping it through the "magic" algorithms. I wonder if somebody on this list could outline what efforts are being made in this area.
