Yeah, I was proposing an implementation using FUSE because this way you 
can make applications wait until a file becomes available before 
allowing them access to it. This would prevent race conditions like 
starting firefox, firefox creating a new profile because the existent 
one hasn't been downloaded yet and then being unable to download the 
original file because the new one is locked.
I consider this essential if you want more functionality than dropbox 
(eg. using owncloud for your whole home directory).

I think it would be orders of magnitude easier and faster to do decent 
file syncing (that is, not too slow) for dot files instead of modifying 
every application out there to use a custom library for saving settings.

The other thing is that at least for the moment I intend to work through 
GSoC, and as this is a KDE project, I suppose my work would need to be 
mostly DE independent or KDE-specific. By the way, are you also a GSoC

Sure. The only thing to keep in mind is that in the context of GSoC 
there's not too much time, so the tasks would need to be fairly discrete.

I was also going to suggest Python, with the mention that I'd like to 
test the disk and network I/O speed more thoroughly.

That sounds like something to use when otherwise things start breaking.

Those being file conflicts?

Almost all applications save user data in dot files. Personally, I have 
switched between different distributions and kept my home directory 
intact for a number of times without encountering any significant 
problem. What we'd need is an option for creating symlinks, because 
files used by the same application might have slightly different names 
on different distributions.

Exciting times ahead :)
