Your still missing the performance implications. In many, many typical cases (and this will become more and more true as memory gets cheaper), it would be far faster to eat the whole tarball and explode it into a bunch of in memory files even to get just a few of the files. Work through the math - if each file costs you a seek, you only need to get to 2-3 files before it would be faster to get 'em all.
