   Michael - I think that we have the same goal, but I disagree with that 
   statement.  I think that re-writing every protocol from discovery 
   through transport to applications, from scratch, is what reinforces the 
   idea that IP isn't an appropriate technology for things.

   I realize that there are pressures from an installed base, but at this 
   point it's a tiny fraction of the overall potential.  If we let the 1% 
   installed base dictate the path for the next 99%, we should do our best 
   to ensure that it's the right path.

Taking these two paragraphs together, you seem to be saying
that IP is an appropriate technology for tomorrow's things,
but not necessarily for today's.  While the hardware will
obviously improve over time, we still need to pick some
target platform.  The current 6lowpan charter gives 32K of
flash as an example and mentions 802.15.4 repeatedly.  Are
you suggesting that we recharter?  

The increasing capabilities of the hardware does give us the
reassuring prospect that the longer we take the solve the
problems the easier it will be to so.
