Dunno, but the guy who created PGP is one of the crew who developed this privacy tool. That alone tells me that it's worth looking into.
Yar, I see good ol’ Phil is there so that is indeed a definite plus. No name for the app, however, and no info if they will release the sourcecode as well. Can’t wait for us ‘Nix sorts to get hold of something to play with, and I hope someone over at SourceForge will have some helpful links soon.
