If you didn't get to go, you can see all of the slide presentations here. This includes slides from the Zigbee-related panel.
My personal favorite was the poster / demo session. Benny Lo from Imperial College London was demo-ing his heartrate/ECG (hope I got that acronym right) that was transmitting data using TinyOS a PocketPC outfitted with a TinyOS-savvy card. Rick Bauer from CENS was transmitting images from a card they've built. Geoff Warner-Allen's group (aka Matt Welsh's group) at Harvard has set up acoustic sensors on a volcano in Equador to sense volcanic activity. David Kosnik was using something I could use today: he had a ratiometric string potentiometer to measure the rate at which cracks are expanding. I live in an old (125yr) house with no foundation; while I'm fairly certain the thing will be standing tomorrow, I'm uncertain about next week... All of the demos / posters are described off the above link.
The TinyOS 2.0 section wasn't news to me, but if you haven't heard about it I recommend reading up on it. On the site menu, click on 'Working Groups' and then 'TinyOS 2.0 Working Group'. You can figure out there how it will affect your work. Also, if you have comments / questions, you can post to tinyos-devel (see the working group page for more info).
My take on TinyOS and Zigbee remains the same post Zigbee panel. In fact, Mike Horton's slide presentation echoed that position: they're compatible technologies. Mike mentioned that Crossbow is working on a Zigbee stack in TinyOS. Joe Polastre questioned how the licensing would work (TinyOS is open-source); that remains an open question. Dave Jim Schoenduve from Chipcon remained, unsurprisingly, agnostic. You can read the panelists' presentations for yourself at the above link.
The winner of the
Crossbow Smartdust Challenge was H2Options. The $10,000 prize (yeah -- start thinking about next year) injected some excitement into the proceedings. Personally, I was rooting from Utah State because if they won folks might realize that Utah is indeed on the internet (though I suspect there is a giant content filter at the state border targeting liberal content).
The only regret that I have is that I didn't get to see all of the demos/posters during the allotted time and I wish I had. Also, if would be interesting to have heard what attendees needed from TinyOS. Alas, no time.
Lunch was an Indian buffet. I love Indian food, so can't beat that.
