Hi,

As a part of research activities the Embedded Systems - Open Platform Group
from Siemens Corporate Technology we are working on adding support for
the IEEE 802.15.4 Wireless Personal Area Networks to the Linux. Our current
implementation is neither certified nor even feature complete. However
we'd like to present current state of our patchset to the Linux developers
community to gain comments, fixes, ideas, etc. This is not yet a pull request,
but more like an RFC.

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.

For now, we do not release any ZigBee implementation. BTW - could you
refer to particular clause of GPL, which doesn't allow user to pay for
code?

    b) You must cause any work that you distribute or publish, that in
    whole or in part contains or is derived from the Program or any
    part thereof, to be licensed as a whole at no charge to all third
    parties under the terms of this License.

You can charge a duplication fee when you do the copying. It is fine
to charge for things like support or the hardware that comes with the
software.

Regards,
Maxim
