OS X Lion Sandboxing
VLC should support better security by incorporating Mac OS X Lion's new Sandboxing and privilege separation features. The decoding of video and audio files do not to have complete access to the complete file system, etc... and should therefor be run a separate secure and sandboxed process as QuickTime X already does for H.264 decoding.
Because this enhancement request relates to security and making use of already available API's, this should be incorporated in a very near future release. (IE: a minor release - not major version release)
