Subject: Centralized server information gathering alternatives / The Bizex worm

Most worms today that infect machines try to report back to centralized
servers specified by the creator (to upload/download data).  The only
problem with this approach is that centralized servers can be shut down to
prevent the spread of the worm and cease information gathering.  Now, what
would happen if worms were "smarter" and instead utilized the BitTorrent
networks?  With a small server client built into the worm payload and
50,000-100,000 infected machines, the author(s) (and even the worm itself)
now has access to the data being harvested without the crutch of a single
(or a few) predetermined access points.  Do you guys think this approach
will be utilized in the more advanced worms of tomorrow?
