I don't think that the ability to skip versions is going to hold long term.

The current setup is that olpc-updte does away with all the post-inst
and related hooks, which means that running code has to have the
smarts to upgrade/downgrade stored data formats (user documents,
configuration options, etc). This can get burdensome quickly.

As of now for example, the promise of olpc-update (of booting back to
the older version sanely) is broken between update-703 and current
joyride as the ds format has changed in an incompatible way, and
update-703 cannot read the new layout.
