Yes this is being worked on. It'll be soon possible to run deltacloud 
like any other library, in process. Plus with the added benefit that 
you're using a project whose developers are highly involved with the 
Fedora community.

Not really, the snapshots are extremely optimized. Only the package list 
is saved plus any files modified outside of the package system. Plus you 
can restrict what exactly is backed up, only backing up your build root 
for example.
