multi-boot Windows-Debian-Ubuntu all encrypted-some success, help needed to complete

Just thought I'd share with you my partial (so far) success with installing encrypted Windows, Debian and Ubuntu multi-boot/triple boot onto a Toshiba NB100 Netbook, 5400rpm SATA.

Idea is that I want all three OSs to keep my skills up-to-date and for work, and encrypted as will put company material on it.

Partitioned drive
Primary partition 1) Windows XP Home, 52Gb
Primary partition 2) Debian /boot, 2Gb
Primary partition 3) Ubuntu /boot, 2Gb
Primary partition 4) Extended partition
Logical partition 1) LVM encrypted Debian installation / root (ext3), 15Gb
Logical partition 2) Ubuntu /root (not encrypted yet)* (ext3), 15Gb
Logical partition 3) LVM encrypted Debian /swap, 2Gb
Logical partition 4) Ubuntu /swap (not encrypted yet)*, 2Gb
Logical partition 5) Share, NTFS, not encrypted yet, 30Gb

*(Ubuntu 8 install doesn't have this option, have to do it later)


Steps:
1) Windows XP already installed as purchased
2) Partitioned using boot it
3) Installed debian and GRUB - to give choice of XP or Debian on booting
4) Installed Ubuntu and GRUB - overwrote Debian GRUB - to give choice of Ubuntu and Windows
4) moved GRUB to debian boot partition http://blog.nikolaidis.com/2008/06/28/moving-grub-from-the-mbr-to-the-install-partition/
5) Encrypted Windows XP with Truecrypt 6, installed Truecrypt bootloader, which asks for password on boot or offers ESC escape key option which takes you to 2 options, Debian or Ubuntu


what I want to do next - any thoughts
Encrypt Ubuntu
Make Debian boot sequence only ask for the LUKS LVM password once, instead of twice: for the main debian filesystem and for the swap

If I find answers I'll update here, but let me know if you have any ideas. Cheers.
