I think it'll be an interesting answer.

I guess there is no incompatibility there. See firefox, the source
code is free software and links to several GPL'd libraries yet the
name and logos are trademarks. After all the DDP is just a protocol
and format specification, I don't see why they should have any rights
pertaining to its implementation other than making sure it's compliant
with the aforementioned specification.

Can't answer that but I think it's possible as long as the library is
not statically linked. That's what the nvidia proprietary driver does…

Thanks for pointing that out. I'll take a closer look and see if it'll
fit my workflow.

Now we need to tackle transfering the resulting DDP to hexabyte since
most plants (in my area) just don't accept DDPs on other medias yet…

If I can be of any help, just ask !
