So as to this the only problem I see is that webmasters would have to
supply up to twice as more space on their servers. (The number of
xdeltas they would maintain would be limited, so that their total size is
not greater than the newest packages's size.) Of course, they would have
to maintain an xdelta for upgrading between every two prior versions (but
what's the issue here?). What they would win is lower network overhead.

And BTW, thanks for the hint, I would have a look the mail archive.
