Which is kind of a shame, as a good binary diff is vastly smaller
than downloading the entire app.
But I'm sure implementing diff support would be harder than on
Windows, because Mac apps are directory trees, not single files. So
the patch process would have to use one diff per file and apply them
recursively. Not rocket science, but a wee bit tricky. (Looks like
Sparkle isn't open source, unfortunately.)
I vaguely remember hearing that 10.5's PackageMaker added support
for binary diffs, or at least for partial updates. Alternately,
Alexandre Colucci wrote an app called iPatch that might help.
