Actually, it should be much simpler than that. The embedded client/server
library (your renamed fbembed.dll) can be an ordinary client to a remote
server. So all you need to be concerned about with your application is
that the parts of the connection string (host name, protocol and db file
path) are configurable. It is very simple to take care of the file path,
using aliases.conf. The host name will be nil for an embedded connection
or a valid hostname for a remote client. The protocol is determined by
whatever the application resolves the connection string to be. If you take
care of these things during development, then migrating a user from the
stand-alone to the client/server model will be a simple matter of, for
example, editing or replacing an ini file on the client machine.
