The core might want to think about the AMID-less radio driver.

Net2 is definitely interested in either upgrading the current code
base with this one or having alternative implementations if there is a
justification for it. I had a brief discussion with Matus, who
maintains lib/net/6lowpan, and there is an interest in understanding
this implementation more. The mote code seems to have more
functionalities and the PC-side code seems based on net2 code. I am
not sure if there is any performance or otherwise comparison between
net2 and Stephen's code. I will setup a discussion between Matus and
Stephen.

Thanks.
