Yes - right now you need to change the code, but I'm willing to
consider other ways as well. It does support multiple repositories

Sounds reasonable. Only way would be to have some way to ensure that
the metadata gets mapped and added correctly by whatever that is
"importing" the books. Incidentally, Get Books supports scanning USB

Yes, with the difference that the search can be done remotely (without
having to have a local cache of the catalog) via OpenSearch.
