More zsync users

MirrorBrain is now offering .zsync files for its downloads . This is exactly the sort of model that I originally had in mind for zsync: file distribution services making .zsync files automatically to enable people to download new versions faster and to reduce their own bandwidth costs.

BAILII has come up with a more unusual use case; they are offering .zsync files for their (in some cases large) RSS feeds. That probably only becomes generally useful if RSS feed readers were to support it; but it would be handy at least for feed aggregators to reduce bandwidth use (and indeed if feed aggregators do use it then it could give a useful bandwidth saving there alone).

And OpenSUSE are using zsync in their new libzypp backend for package downloads. I need to find time to have a look at the code for that...
