This has nothing with any sort of logging in.

And it has nothing with the way URI data is passed to add fro.

That's right. It's my job to specify the relationship, not the user's/client's. So this rules out the Class.forName() on the user's/client's side, right? The client should be oblivious of the implementing class itself. The only thing the user/client is required to know is the structure of the URI. 

After that, the FileSystem (regardless of the actual implementing class) can be obtained by calling FileSystems.getFileSystem(URI).

All I want is to know if that's possible. And if it is, how it can be done.
