I think I have enough free space to juggle things.  I've got the
rootfs and swap on LVM and have tons of free space.  In theory I could
shrink the rootfs ext3, shrink the LogVol00 containing that ext3, and
create a new logical volume to contain /home that I intend to encrypt.
While I'm at it I'll also encrypt swap, but with an ephemeral key that
gets pulled from /dev/random on each boot.

Thanks!  I think that's the key I needed.
