I was serious: you can't put any obligation you want in a SW license and hope it can be enforced against those who buy said license. And it has been debated whether restriction to run consumer general purpose software on specific hardware, especially when that sw can be obtained independently of any hardware, can be enforced or not.
Yes I remember bringing up a software license with a lawyer I was talking to some years ago for a product I was selling - he laughed. I don't know if it's changed much since then - most of that stuff is untested in court AFAIK
It seems strange to worry about licensing in a community predicated on violating a term of an OS license.
Is this a problem because source code isn't available?
