well my thought is, more the botnet side of it, IE pushing less on individual machines, but more on massive distribution. IE it not needing one computer strong enough to run it, IE expecting 90% of the machines it infects to be average consumer PCs, but making more use out of 1000 systems that can handle 1% each, rather than 1 computer that handles 100%, however yeah I do suppose also allowing it to do the bulk of the work when the computer is likely unused etc... and I don't know much on the concept of communication etc... IE most major botnets were crushed by a command center being shut down. Imagining a different form that has, basically makes C&C's on the fly.
