While I think this is a cool solution for private or trusted usage, I do see two issues for enterprise usage due to aufs:
Minor: It might happen, that some log-file runs crazy and fills the ram. In this case a reboot will solve the issue. This might be unwanted, though.
Installing any kind of software is much easier, as more directories are writeable then with the tmpfs-solution. Once someone does become root (already having an anonymous login) the world is open... :)

Last friday we've been experimenting with creating thin clients using the live-build infrastructure. This is the infrastrucutre that is used by both debian live and from oneiric onwards, the ubuntu live cds. This worked included backporting relevant packages from oneiric to natty and fixing some annoying bugs for getting actual working packages.
Mainly as a self reminder for me, here some test instructions for *natty* systems. Feedback (as always) welcome:
sudo add-apt-repository ppa:siretart sudo apt-get update sudo apt-get dist-upgrade sudo apt-get install live-build x2go-rootfs mkdir /tmp/build cd /tmp/build cp -rv /usr/share/x2go-livefs/auto . sudo lb clean lb config sudo lb build
after this, you should end up with a lubuntu/natty based live cd 'binary-hybrid.iso' that has an lxdm configured to autologin the user 'user'. Moreover, x2goclient and rdesktop should be available in the system. This binary-hybrid.iso is for me less than 500MiB in size and AFAIUI (but I didn't test myself) should also worke from an usb stick (dd if=binary-hybrid of=/dev/sdX).
hints: /tmp/build is best done on a tmpfs. You'll need around 2gb space available there.
Cheers
