Well, it could be implemented with a FUSE daemon, that you mount over
/usr for example, and which periodically fetches the Contents-<arch>.gz
file from a mirror. It the uses the Contents file to generate directory
listings. If some package tries to open() a file that is not already in
the original /usr filesystem, it will look into the Contents file to
determine which package contains the open()ed file, installs it, and
then lets the open() continue. It can also track usage information this
way. It's a daemon that you can start as root during boot, so users
don't need special privileges. Also, if you stop the daemon, the
original /usr filesystem becomes visible again, which can be used
without problems.
I'm not going to implement this though.
