Hi Jari, Just a little more information on the open issues:

Our draft cannot solve key management for the Internet, so perhaps it is better not to prescribe too much. > - MLD (many). This has been discussed on the list.

The idea is the MLD must be supported. MLD is needed for multicast services. MLD usage on link-local addresses, however, may not be useful. > - RFC 3041 stronger statement (IESG).

More correctly, cellular hosts can have two kinds of radio attachments to the 3GPP network - primary and secondary. Secondary most likely will be short lived. The primary may be longer lived, but depends upon radio coverage (radio coverage is usually lost when going through a tunnel), user behavior (if the user turns their phone off during a meeting, or at night), etc. These attachements to the network will deterimine the lifetime of these addresses. In summary, cellular hosts should support temporary addresses as outlined in 3041. However, I don't feel confident enough to detail how they are used. I think we need usage / deployment experience.
