ROLLers,
  Did anyone see the Cisco announcement about IPR in RPL.  If you didn't it was probably because it was only sent to the IETF IPR list.  I don't know why it wasn't sent to the ROLL list.  If you didn't see it here is a link:

http://www.ietf.org/mail-archive/web/ipr-announce/current/msg00167.html

I'm a bit confused and concerned that this IPR annoucement was sent so late in the process (December 3).  Given that Cisco folks were working on the design team from the beginning why did it take so long for cisco to identify the IPR.  We are now so late in the design and development that it would be nearly impossible for us to figure out how avoid this patent.

There is a free license to use the patent in RPL so long as you and your company doesn't sue Cisco over ANY other patent for ANYTHING.

Can we avoid the use of the patented technology in RPL?  Should we?  Do we want to?

Did this IPR announcement come too late?
