There are a couple of issues in the patch, but my concern is about
not having all hardcoded stuf (not only for dextrose but, eg, for OLPC's
XS) in shell code and relying only on command line API (the reason is
that this command might be called w/o shell's UI at all and might have
quite different release schedule in comapring w/ shell).

In other words, it will be useful to:

* rehash such code in Dextrose patch (for updater and school server backups)
* rehash XS related code
* create a Feature/ page on SL wiki for such refactoring/adding-new-code
* in Feature's code, use sugar-client[1] command line API to all
  interactions with [school] server (and hide such UI if sugar-client
  command doesn't exist)
