License? Seems hard to find online. Not looking for anything unusual for the existing raspi community, just what do I have to do to make a project on it then distribute a bootable sdcard image to users around the world for free. I'm guessing its a total non-starter but if I were surprised by it being BSD/GPL that would be interesting. The hardware compatibility part of the release notes look like a bad linux install from 1995, which is pretty funny.
