This is not fully baked yet but I thought I'd at least throw it out there as a
topic for discussion. I think we've focused almost entirely on single images
so I think it's worth thinking a little about different storage models.
Wouldn't it make sense to have your file system be that daemon
I see that as purely an implementation detail.

and add an interface to it so you can receive the sha1 sums (that you need
for dedup anyways) to calculate rsync style diffs?
That way you'd also speed up 2 other use cases:
a) normal raw storage - no need to implement new protocols, file formats, etc
b) real rsync on real data that is not vm images
