I'd be sane to treat these containers like directories. Directories are just another kind of container. Given a tarball baz.tgz in /foo/bar containing the files a and b/c you'd tell the user about matches in the paths /foo/bar/baz.tgz/a and /foo/bar/baz.tgz/b/c. I think Windows "Compressed Folders" work like this.

I could see using "foo.gz" as the filename for a standalone file, using your streaming method.

For tarballs, though, I would have to extract to a temporary directory and delve through that, and that means write privileges that I don't want to assume.

You can't extract a file at a time out to a temporary directory using File::Temp? Or even better - don't even write it back to disk.
