AFAIK, p7zip attempts to track 7zip sources closely and merge stuff. But even if it forked, it'd be very unlikely (and counter-productive) to also fork the file format specs. I don't think 7zip maintainers have a problem integrating streaming support if it doesn't break anything (but if you're concerned about that, never hurts to ask..) Please let me know if you add that wrapper script. -- Robert Millan
