I think that this is probably the best route for you to take at
present. We are in the process of developing a full filesystem
interface specification that will do what you need. I don't want you
to spend too much time trying to squeeze your code into the current
structure when things are going to change for the better in the
Of course you have sources and can so what you want with them! But the
fewer changes you have to make to the distribute sources, and the more
you concentrate in your own code, the easier it will be for you to
take new versions.
