I think that's an issue I ran into earlier when I was trying to run all 4 of my pods off a pi. Never could get it working and I had to split it between 2 Pi's.
Anyone know if there is a way to figure out bandwith from both internet usage (I use a wireless connection) and USB traffic to calculate where I would get into trouble? I don't like doing it by trial and error and realizing I have to buy new equipment halfway through.
