Hi,

we have implemented 

  http://tools.ietf.org/html/draft-schoenw-6lowpan-mib-03

on Contiki and we have put an AVR Raven online so you can throw
packets at it. For the details how to talk to this device see this
page:

  http://cnds.eecs.jacobs-university.de/the-6lowpan-mib-testbed/

We believe it would be very useful to agree on the counters defined in
the MIB module (even if you prefer to ship data using a different
protocol). The key is finding agreement on the counters needed and how
they interact. This is best summarized by this piece of ASCII art
(copied from the above I-D):

                             IPv6 layer
                         ^               v

Feedback is most welcome. (If the demo fails, please send us private
emails and we will take a look at things.)
