A possible answer would be to abstract ALSOParse.py and microformat.py
as back ends for Sugar-Update-Control (SUC).

SUC could either fall back from ASLO to microformat or be configured
to connect to either ASLO or microformat by default.

A third alternative would be to add a local-server backend.  It would
be pretty straight forward to write a script to poll ASLO for
available updates, create a text file of available update, and
download the updates to a directory.  This data could then be moved to
individual deployments as needed.

SUC could then update individual machines from a local server using
data created above.

I'll start working on abstracting out the backends today.
