That's a bit tricky. There are three points that would have to be shared: the
userspace miscdev interface, the backing filesystem and the single index tree.

It's probably easier to just have a go at converting 9P and cifs. Making the
old and new APIs share would be a fairly hefty undertaking in its own right.
