Re: [Roll] 6LowApp: Application protocols for 6LoWPAN and other LLN

Hi carsten,

I would like to present the timeline and requirements for the zigbee smart energy work.  Should be not more than 5 slides and 15 minutes.

Based on the extensive feedback I got for the 6LowApp Bar BOF, I have  
slightly extended the problem statement:

http://u.nu/2bfj  =
http://www.ietf.org/internet-drafts/draft-bormann-6lowpan-6lowapp-problem-01.txt

Thanks to all the additional contributors. (I don't agree with all  
their comments, but I tried to err on the side of capturing as many  
requirements as possible.)

The Bar BOF is still scheduled at ->Tue 18:30<-.
I'm going to ask the ADs for a room so we can hear each other (and  
maybe use a projector).
Again, please tell me if you want a slot in the structured part.

Even after the I-D deadline, you can continue to capture information  
at the Bar BOF Wiki:
http://u.nu/6jfh  =
