Re: [pim] agenda requests for Montreal

Hi

I think this is a good topic and should hopefully be an interesting
discussion. It would be good to see if people agree that deployments
should use IGMPv3/MLDv2, and to what extent and how strongly we should
discourage the older versions. I also would like to see if there is
interest in advancing IGMPv3/MLDv2 on the standards track. This may
require us to find volunteers (Toerless and others) to work on related
drafts.

Perhaps you should consider a slot in mboned as well, as this has a
lot to do with deployment?
