I think the only reason that the amiga roms are still not free is because the company that purchased them "KMOS" is going to be using it, here is a quote from the offical Amiga OS site.
"This unique technology is currently being adapted for the next generation of mobile communication chip sets, ushering in new forms of mobile communication"
Unless Im wrong it looks like there going to develop the Amiga os further and intergrate it into new technology.
Here is a link that shows the Amiga OS 4.0. If you read some of the site I think there will be a future in it!..
