what about a /home on a stick option. if you plug in the USB stick then it auto boots your desktop enviroment on whatever buntu... even a Live CD..

/nomad

what it is: a dir like /nomad/*username*/home and it holds a copy of all the users documents and configs

the way it works
Load a live CD or a Ubuntu until before the login, then plug in the /nomad stick, Ubuntu sees /nomad and it knows now i must log in with this users config (for me this would be like, no wallpaper, no eyecandy fx in gnome, a tuned firefox, eventually a pidgin config, etc.)

Ubuntu should offer to remove software I once used and now forgot to remove. Graphical apps that show up in the menu I don't forget that much, but I usually install whole shiploads of cli apps that I think I need, which makes my PC slower.

To realise this, Ubuntu should take notes of every app that's started, excluding system apps (echo, ls, cat).

I was not able to create a writeable share as my normal user, which is a problem in itself. To circumvent the problem, I create the share as the root. Now the folder is shared, but my user account does not know it. It does not show the icon on the folder saying that it is shared, nor does the sharing options menu say that it is shared. This is a potential security risk because you can create shares through root and the users would know nothing about them.
The user needs to know which folders are being shared.
