We did have, apart from draft-schmidt-multimob-fmipv6-pfmipv6-multicast, several other multicast handover solution drafts such as: http://tools.ietf.org/html/draft-vonhugo-multimob-cxtp-extension-01
This draft basically uses the context transfer protocol (RFC4067) to carry multicast state between ARs/MAGs. No full handover operations have been specified. At the unicast side, RFC4067 is a predecessor of the more advanced Fast Handover Protocols does not apply to unicast handover management.... IMO it does not make much sense to consider this rather elementary approach any further.

This draft is - if you want so - a competitor to draft-schmidt-multimob-fmipv6-pfmipv6-multicast, but has never been worked out (as have several other attempts in the past). If this document was to be advanced, it had to rewrite (or copy ??) 80 % of our draft, which is not a proper way to treat authorship.
If we decide to accept more than one handover solution then we probably need to consider all of them for possible WG adoption.
I don't understand your thinking here: it is perfectly normal that there are competing approaches and the idea of the IETF discussion is to have the best solution win. From the performance side, and from protocol systematics (cooperation with unicast), draft-schmidt-multimob-fmipv6-pfmipv6-multicast is clearly the best solution for fast handover operations - this comparison includes the adopted draft "fast handover from transient binding".
