I was wondering if cvsfs is for me.

I need a "file system", which allows multiple people to work on one document, resolving conflicts in some way.

For example we have a rw directory and a file:

rw /data/document.txt

If person A edits this documents and saves it, it should be automatically saved as two files:

ro /data/$username-2005.12.22-14:56/document.txt
rw /data/document.txt

Can I do something similar to that with cvsfs?
