The questions I'd like to see answered are:

1. From our talking you indicated that FUSE has both high-level and low-
level API.  However, the post only hints at it.  Could you explain both
shortly and why you've chosen the one you've chosen?

2. How are you planning to deal with the essential problem that
the underlying directory tree may consist of multiple filesystems with
different files having colliding inode numbers?

3. How do other passthrough filesystems deal with the same problem?
 What are the advantages/disadvantages of different approaches you've
considered, and why did you chose this solution?
