You are correct, I should have said "could hypothetically." Or as an optimist, I might say, "will, one day soon."
And it's not simply using CouchDB. The application must also permit users to replicate. For example, a Couch app might be allowed for browser access but replication is blocked by a firewall. The developer must both use CouchDB *and* respect your freedom. Still, I think that day is coming.
