As things stand, it is not possible to achieve what you are looking for
with DHT. By using regexes, you can influence the placement of files
relative to other filenames *only within the same directory* (thereby
making temp file followed by rename inexpensive, etc.)

What you are looking for requires a major change in DHT - using a single
hash layout for all directories and not having a directory-specific
component in the hash calculation.

Thanks,
Avati
