Sorry I don't understand this. What filesystem are you using?

I'd personally just use copyparty, but this does seem to have a different feature set that probably makes it a better fit for some uses

Does it conform to Orthodox file manager specs? http://www.softpanorama.org/OFM/

Web based file manager. I think I've seen everything now.

Anyhow - good luck, I bet there are people who want this.
