I'm assuming that you're referring here to getting zchunk packaged into Fedora. I'd really like to finalize the file format (we're close, but I still need a good way of storing signatures in it) and the download API before releasing it into Fedora proper. I would recommend using the dicts mentioned above as they give me over 40% space savings for both other.xml.zck and primary.xml.zck. Do please let me know if you run into any problems.
