In an ideal world ...

Unfortunately, it doesn't really work like that. If you were compiling
everything from source then you might be able to take advantage of
common code (though only if rsync can see inside .tar.gz files, which I
rather doubt somehow).

However, I suspect you're collecting binary packages. In that case then
the fact that most packages will have been recompiled for glibc2.1
between slink and potato, and that rsync won't be able to deal with
those differences efficiently either, will clobber you too.

In a few cases you'll get lucky: xcdroast, as you mention, is the same
version in both distributions, so you won't need to download it again.
But by and large I'm afraid you'll just have to do the full downloads.
