Re: IGMPv3 for really dumb hosts

The -lite of igmpv3/mldv2 would contribute to the SSM deployment on
some level. And I could agree to eliminate an EXCLUDE mode (although
EX(null) is needed).

However, -lite must keep an interoperability with the full versions
without requiring any change on the full versions.
If we define different message types or different usage of the message
types used by the full versions, it may be difficult to fulfill the
condition.

Actually, I did a quick review of Hui's draft, but unfortunately I
could not agree several interpretation, because it seems the draft
proposes different protocol bahaviors and different usage of the
record types, which implies something new protocol and includes
difficulties for the interoperability with the full version.

For your question, igmpv3/mldv2 for dumb hosts; as a host-side
protocol implementer, I'd try to illustrate how -lite version should
be designed on them.
