Just after a very short time running a ASIC will be profitable with free electricity only.
Team up with a student in a dorm room or a single mom in a state-sponsored house LOL

Unless I messed up the numbers a Jupiter with 350 GH/s and 1000 W power consumption, should turn a profit until difficulty is over 4 Billion. While the extra profit of no electricity cost would be nice, I think I'm good for a while.

I think you fucked up. My calculations say that at 1.5 billion difficulty the Jupiter would not turn a profit even if the price was 350 USD/btc
