The Zigbee alliance requires a minimum of $3,500/yr from any company
making a product based on the spec. How are you going to reconcile
this requirement with the GPL? They exempt non-commercial users but
the GPL doesn't allow code to be free for one purpose and pay for
another.

errata may not have been subjected to an Intellectual Property review,
