POSIX has lot of methods, i did not found a more HTTP-compliant way to deal with it. If you have ideas feel free to expose them, i would be really happy to simplify the specs.
Regarding 9P, SpockFS is a fork of the 9spock project (unfortunately my company still did not released the sources, albeit the github repository is opened), and personally i think 9p is the currently best protocol available for sharing filesystems. Unfortunately the linux client is a bit weak as it does not manage disconnections/reconnections (once you lose the connection with the server you have to remount it)
