Companies need to make money, and in a market where we can't count on mass sales (unlike the PC clone and Microsoft markets) there has to be some give. The license fee for a hardware producer to run an OS is perfectly viable. I'm sure hardware phone manufacturers have to pay certain royalties for using an OS on their system.
At the end of the day the only current license for new PPC based OS4 systems is Eyetech's Amiga One. If YOUR REQUIRED OS wont run on on your PREFERRED hardware then I can only say that you purchased the wrong board.
If you bought a board to run operating system X, and then Y comes out requiring the manufacturer to pay a fee for use on the system, then you need to talk to the hardware manufacturer. If this cannot be resolved then you need to rethink, or hope that the manufacturer comes to some agreement (ie: pays the fee).
Don't get me wrong I want to see AOS everywhere, but business is money and without money we won't see AOS anywhere.
