Free beer is good!
One thing you guys didn't mention yet:
In order to become a "private" developer for the iLiad platform (and receive the SDK), you need to register with them and own an iLiad device, where the "development environment" is being downloaded from.
So if you don't have an iLiad, you won't get to see the SDK. Bad luck, guess we have to stick to our free beer. The big question: is this way of releasing the sources and development tools in compliance with GPL?
