blank for a local connection, and fill it in for a remote
connection. Wouldn't my logic be correct for that? If the remote client
omits the Server entry, I would EXPECT it to look for a local server, and
return an error message if the server (or database file) doesn't exist.

Database path and protocol from what? Shouldn't I set the Server and Path
based on the user's input?
