[Tinyos-2.0wg] blocking items for 2.0 release

[Philip Levis]

In the call today, David C. noted that we should try to remove the  
blocking items for a 2.0 release in order to keep it on track. Here's  
the current list of things that we've so far agreed are needed for 2.0:

Deluge
Surge-like app
Sensor board support
Completed tutorials
Power management for virtualized devices (low power CC2420?)
   - HIL power management for the radio
Radio metadata
Test/evaluate that power management works and doesn't have gotchyas  
(so far seems fine)

Bonus items:
Security
Test suite

For the most part, a lot of this just involves writing code. I have a  
student working on a Surge-like app, and should have some updates  
soon. Kevin has been evaluating power management, and it sounds like  
will soon be able to check in the arbitration updates. I will prod  
Martin about sensor boards for the mica family. The really big ones  
that nobody has actively picked up are:

Top-half of Deluge (large-item dissemination): this might be in  
net2's camp, but I don't know who in net2 will do it. I'm currently  
firing cylinders on collection, and that's where a good deal of the  
effort is. This will require someone stepping up to the plate to  
drive it forward. I think that person will be able to get help, but  
it needs a leader.

A low power radio stack for the CC2420. I'm not sure if I'm really  
comfortable with releasing 2.0 unless we have demonstrated that it's  
possible to implement a reasonable low-power solution on the CC2420  
with the current interfaces, given how heavily used the chip is. Push  
comes to shove, we may have to release without it, but that seems  
like a bad idea...

It would be good to get updates on the status of a few TEPs:

105: David, do you have a timeline for getting a draft to the group?
109: Gil and David, this is a blocking item for Crossbow to make  
progress on sensor boards
122: What's the status on the unique ID TEP? Haven't heard much since  
the initial round of comments.

I chatted with Rodrigo today, and the net2 group is producing another  
Documentary TEP, TEP 123, on collection protocols. The tentative  
names are CTP (collection tree protocol) and RCTP (rooted collection  
tree protocol), but those are very likely to change.
