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 = http://trac.tools.ietf.org/area/app/trac/wiki/BarBofs/IETF75/6LowApp Gruesse, Carsten On Jul 6, 2009, at 12:56, Carsten Bormann wrote: > The 6LoWPAN and ROLL WGs are laying the groundwork to make the > Wireless Embedded Internet a reality, but what application protocols > will we use?
