dirvish looks interesting. One of the requirements that I now realize I didn't write into the proposal was the ability to store only a single copy of duplicate files... duplicate as determined by file contents, not naming or inode or anything. (Rationale: will likely need to back up large numbers of clients with lots of files in common.) Dirvish does not appear to have that capability, but it *does* appear to solve the right problem. Extending Dirvish to make hard links from the image into a directory tree based on SHA1 hash might work to implement this. [snip] > Ever hear of vfs?

I'm not sure if you are referring to one of these or something else. It definitely sounds like something to investigate, could you send a link? [snip] > Forget it.

I'm pondering these ideas of plugins plus the ideas Andy put in his post. I might be able to make the system out of it with less hacking-and-slashing in code.

I'm not trying to force patches on you guys (not that I even could). I basically have to solve a problem for a client and would like to do so in a way that I can most benefit the rsync project (or another project if rsync isn't the "right" project). You seem to be unduly afraid that I have some sort of power here, and really all I can do is take my marbles and go home. Well, perhaps I could spam you with awful patches, too ;-) -- Jason M.
