Legitimate botnet (zombie) farming?
Is there a company doing legitimate zombie farming? ie, a cloud of computers running a local server which process data from a centralised distributor? People do it illegally, selling processing power from trojan infected machines, but is anyone doing it as a legal business?
Imagine you could download a small application which sits in memory and draws off a certain percentage of your CPUs runtime, depending on the machine's usage. This processing power would form part of a cloud sourced supercomputer, with runtime sold to whoever. And say you were paid maybe a couple of dollars per 24 hours of processing, depending on CPU speed. Leaving a couple computers on 24 7 would add up to a not inconsiderable sum per month. You could salvage some old machines and leave them going in the basement.
I've worked at animation studios, as an example, and for sure they would be keen to, rather than intermittently hire a room full of fast machines as a render farm, outsource it to a cloud.
SETI did it.
Like I say, if this isn't already being done, it will be soon.
