Correct me if I am wrong, this tutorial seems to be a bit ambiguous on the point, but would you loose persistence if you simply dd the iso? If not where is the storage for this located, or is it just a full-type of installation? If it is a full installation then this would mean that either you loose a journaling ext3/4 fs on the usb, or it will become inaccessible via windows (on a typical installation, and where the user doesn't have admin rights)...correct? If it is ever a goal to be able to boot via a virtual machine on windows wouldn't this make that impossible? I may just not be understanding you correctly, in which case my apologies. I do think that a full installation has more drawbacks than it seems initially. For example wouldn't it be very easy to upgrade the current overlay method, by just replacing the iso? This could also make it very easy for teachers to customize the activities of the students. -Alexander Pirdy
