The place to customize listing the contents of a directory is in the shell. More specifically, in an implementation of IFTPShell.list. It's almost certainly the case that you should *not* have a FilePath subclass with overridden methods. Instead, you should have a `list` implementation on your shell that returns the desired results. And since `IFTPShell.list` is allowed to return a Deferred, you no longer have a problem performing asynchronous operations.
