The server-side entry point is org.eclipse.emf.cdo.server.CDOServerExporter.exportRepository(OutputStream). You can see
that it's only called by the CDOCommandProvider, but you could
1) Implement your own client/server protocol (e.g. with Net4j) to trigger a CDOServerExporter from a client.
2) Implement a CDORemoteSessionMessage-based protocol between a client and a server-embedded client to do the same.
3) Use telnet or something to gain access to the server console and use the shipped CDOCommandProvider.

No, but syntax help is displayed on the console.

This could be comparingly simple if you make use of the newer IRepository.Props.SERIALIZE_COMMITS option/feature. Could
be a nice contribution to CDO ;-)
