My first thought: Neat, would love to see this implemented! :D

My second thought: it's surprising that IceCat supposedly changes so 
much between releases.  I suppose the reason is that this analysis is on 
a per-file basis, and IceCat is mostly a massive binary.  That leads me 
to wonder: what about binary diffs for large files?

Perhaps for all files that are bigger than N bytes, we could check if 
the binary diff is X% or smaller of the total size, and if so, the build 
servers could host the diff file alongside the full file.  (Substitute N 
and X for sensible values, like maybe 5 MB and 50%.)

But that could be a second, separate step I suppose.
