Hi All,

Agree with most of the problem statement.  Two imbedded comments:

I think we need to scope out the particular design aspects that we
will consider in order to have a focused effort.  Please 
refer to my email on 'DT Directions' for a suggested outline.  

I believe that we should tack on timelines and milestones to help
us be effective.

I hope we consider performance of the technology, and not reject a
design just because it has an IPR statement attached to it.  Especially,
since many IPR claims are purely defensive...as is Cisco's.

Thanks!
