[SensorNetArch] Plan

[David Culler]

We need to get more of the meet into the network protocol sections so 
that we can digest it and think through the implications.  Your new 
stuff will help that a lot.  Those sections should hit: what the network 
protocol does, how it utilizes SP to do the right thing for both links, 
and (in eval) look at how great the numbers are.

We need to deal directly with the role of broadcast on various links and 
what it means for address free protocols.

The BMAC issues of controlling RTS/CTS, fragmentation, Backoff etc. 
don't show up anywhere here.  Is that below SP?  Are those the 
equivalent of the games we play with 15.4 slots?

We have said that every node responds to its address and the broadcast 
address.  this is certainly a common link characteristic.  What does 
this mean for a multiple name per node model?

When are we in a place where we can beat our heads against the remaining 
open issues?
