    Sorry I did not find your talk sooner. Actually, I was interested in setting up a home lab to discover beneficial uses of botnets to push and operate software in real time. Do you know any good code to start out? I think that I want to use IRC protocol for faster communication and I will have a very limited number of computers/VMs. I want to test it to control and tune complex programs remotely. I’d e-mailed a few other researchers studying this but never heard back. Any help would be greatly appreciated.
