Hi Nathan -

I talked through the design with Nikita.  After he had understood our
constraints and I had understood his issues it all narrowed down to one
important improvement that Nikita suggests:  we must get a fast way to
compute the pathname of a FID.  The scanning and searching I suggested
without an index is not tenable.

We had a couple of suggestions, such as storing parent fid and a name in the
EA, or storing similar information in a large directory file.

Can you connect with Nikita and do this?

Peter
