That just works as long as the mobo (sn/uuid) stays the same.

Also works but child will need help from teacher (actually, a user
with "course creator" privileges) to "connect" his old account to the
new one.

So second scenario looks like

  1. child's XO stuffs up
  2. XO's hw is replaced (different sn/uuid)
  3. XO is registered again against the XS
  3.1 course-creator "connects" the accounts
  4. XO has its backups restored from the XS
  5. collaboration, classroom segregation, etc. work as before

I wonder who architected this gem... ;-)
