I must note that Windows XP has a built-in un-zipper.  Drop a .zip archive
to your hard drive on XP, and you can navigate it as you would a directory,
in Windows Explorer.

I'm not sure how this interacts with encryption though.  But it's food for
thought - unzipping is becoming much easier for Joe User.
