I have the same use case for LVM: I want to encrypt both / and swap, but only enter my passphrase once at boot time. If that works without LVM, I'd happily stop using LVM.

Several encrypted partitions with one password and derived keys

On my Arch Linux and Ubuntu systems this works with "derived keys" see here: http://crunchbang.org/forums/viewtopic.php?id=4299 for a well written howto. It's a bit dated (now there is 'cryptsetup luksHeaderBackup') but still works.
But I remember reading that systemd did not support the "keyscript" option in /etc/crypttab, which is needed in this setup. Hope this is fixed by the time I upgrade to systemd on my Arch system.
