Administering my meager farm of 2 machines has been relatively simple so far and boincstats BAM is pretty effortless. All of my machines are going to be at my home, so that makes it easier on me. I plan on using a combination of vnc and ssh in a mix of windows and linux (cuz it's free!).
The point I was trying to make about being on vacation was that the only way I can add my machines to the competition would be to let a friend or family come in and turn my boxes on for that duration. I will be incommunicado with no connectivity to my home network at all.
I'm not setup yet to allow for 24/7 running due to the summer heat unfortunately. I was going to either try a separately AC'd room or the garage. Not sure yet. When I crunched in the past, I just left a bunch of machines at work where it was nice and cool. Doing this at home takes a lot more planning. It makes me feel like such a newb.
