Binaries can be handled with xdelta:

-----------------------------------------------------------------
XDelta(1)                                               XDelta(1)

NAME
       xdelta - Invoke XDelta

SYNOPSIS
       xdelta subcommand [ option...  ] [ operand...  ]

DESCRIPTION
       XDelta  provides  the ability to generate deltas between a
       pair of files and later apply those deltas.   It  operates
       similar  to  the  diff  and  patch  commands, but works on
       binary files and does not produce a human readable output.

       XDelta  has  two  subcommands,  delta  and  patch.   Delta
       accepts two  files  and  produces  a  delta,  while  patch
       accepts  one  original  file  and a delta and produces the
       other file.  As opposed to the the diff(1)  format,  which
       can usually be reversed, these deltas are one way.

Any sufficiently well-rigged demo is indistinguishable from
advanced technology.
