Ah I know (that it would make it proprietary), but I thought there was a way to dual license to make it open in the case of personal/educational use and require payment for professional use? If companies work to maximize profit and minimize costs, I wouldn't bet on them wanting to pay for a license just to have an identical copy of the software (with no value add). I also realize that I can provide that value-add with support -- thanks for pointing that out, it's definitely something to consider.
