Web File System

[anthony.cutrone at gmail.com]

Hi group,

I have a development with a file system in Python, accessible from a 
graphic web application.

I mustn't use an NTFS or EXT3 system, because those are not adapted 
for my use. Indeed, I would like my system to be able to recover 
files, and get precedent versions. I also want it to index words 
contained in files, to search with these.

Files and folders have to be in an SQL database, mounted in ext3-like 
system. File would be identified by a single ID, and links with names 
should be connected on these IDs.

Somebody have already worked (in Python) about this kind of things ? 
is there a publicly available framework or toolkit ?

thanks
