I'd like to make room on a new HD for at least two Fedora installs

virtualized), so that when F8 appears, I can safely install it without
wiping out F7 (and so on, always doing a clean install of F(n+1) on
the space used by F(n-1), leaving Fn intact). I'd like to share /home
and perhaps /tmp between them, and for the rest, to be able to mount,
say Fedora #2's /usr in Fedora #1 as /os2/usr.
Is there a sane way of achieving this? Especially wrt grub?
Off course there is, for some definitions of sane ((-: Take a look at
my grub.conf, sanitized to remove duplicate kernels.

Now I do not share /home as problems may occur, however my UIDs and
GIDs are consistent across distros. I guess you can share /tmp as it
is supposed to be
cleaned out on reboot. Partitions from different distros are added
after I install a new distro and not from the install. I also have a
partition, /downloads, that is shared across all distros. That is
where I keep the isos I install from. No need to burn them, I install
from harddrive.
