That would not seem to control separation well.  How easy would it be
for another student to submit work on behalf of another, or corrupt
existing work by accident?

For a truly shared computer, I suggest switching to a login screen
before Sugar, such as that provided by the default Fedora (before OLPC
OS removed it).

For XO-1.5, a 4GB SD card per student might be another alternative;
when the card is inserted before power on, the laptop could be made to
behave with the identity of that student.  This is costly, and risky,
but is available immediately with no unusual configuration.
