I have been working on setting up a USB or SD to act as a portable Dual Mode Sugar on a stick.

see: http://wiki.sugarlabs.org/go/Sugar_on_a_Stick/Getting_Involved/Testing/Soas-...

There are several improvements that would make this a more easily used format:

* Have a way to disable the live user account in a SD or USB stick (created with Fedora Live USB Creator) if it has a persistence file after a User account has been created.

* a way to remove the un-deletable "Install to hard disk" icon. There is always the danger a user would click on this and damage the underlying OS on the machine it is plugged into.

* allow system updates to occur with out destroying the USB or SD installation.

I hope that these are changes in liveusb-creator are possible as it would turn a USB or SD card into a fully portable F11 beta with Sugar Desktop for Students and other users.
