[Bug 793844] [NEW] use of diff-algorithm

[uhu]

Public bug reported:

Binary package hint: update-manager

It's not a bug, but I was wondering whether anybody has thought of using
a diff-algorithm for making updates, for example as described here:

 http://www.daemonology.net/bsdiff/
or
 http://www.daemonology.net/papers/thesis.pdf
 
I don't have any knowledge concerning this but perhaps the person writing the thesis.

I only ask because perhaps it is more economical just to transfer
changes than the whole package, even for binary files.
