There have not been many announcements about the Cozy desktop file sync client, so I don't know how far it has already developed. But I was thinking today...
Canonical decided a little while ago not to compete with other large corporations in the file sharing market, and so decided to close down the Ubuntu One service. But the
source code for Ubuntu One is still around. I imagine the Ubuntu One servers were configured in a very different way from Cozy servers, but still I wonder if it might be valuable to look at how the Ubuntu One desktop client worked. Perhaps some of the code could be reused? Or maybe it would just offer an interesting perspective of how to build a desktop file sync client? When I used Ubuntu One, one thing I thought was interesting was that you didn't have to store all your data in a single folder; you could pick directories in the local system, and the Ubuntu One client would synchronize them.
It's just a thought that occurred to me, so I thought I'd share. What do the rest of you think?
