My roommate and I also have a shared distfiles.  We clean daily by placing 
the following script in /etc/cron.daily:
#!/bin/sh

if [ -x /usr/bin/eclean ]; then
        # If you want you can also add a grace period,
        # so files downloaded within
        # the last week (e.g.) will not be deleted.
        /usr/bin/eclean -q distfiles
else
        echo 'eclean not found in expected location; not cleaning 
distfiles.' >2
        exit 1
fi

Non-destructive mode uses the portage tree (that is, if any existent ebuild 
could use the file, it stays).  IIRC, this includes overlays, but may not 
include installed packages no longer in the tree.

Destructive mode does use the database of installed packages, so it won't 
remove anything needed by the ebuild(s) you currently have installed.
