If they're big enough, you could use Slony and PostgreSQL on the
devices, which has the nice property of disallowing any attempts at
writing.

If you're not using PostgreSQL for the smaller systems, you might be
able to rig something up with pg_dump using the --inserts option.  The
tough part will probably be getting the schema translated into SQLite
(or whatever system you choose) idiom.

You might also consider DBI-Link, but I'm pretty sure that's not a fit
for this case.
