Two answers:

  1. There may be several solutions for different scenarios on the same 
problem scope, as the unicast-people worked out several solutions (i.e., 
MIPSHOP worked out the (P)FMIPv6 handover solution and the transient 
binding in parallel.

  2. draft-hui-multimob-fast-handover-04 has never been worked out. In 
fact, it merely repeats incomplete work that has been around for years, 
the first draft with incomplete sketches on fast handover has been 
http://tools.ietf.org/html/draft-suh-mipshop-fmcast-mip6-00 in 2004!

So the argument we were presenting is: there is reason and need for this 
fast handover solution, and we should adopt the document that is most 
mature, completely worked out and discussed many times in the WG.

Cheers,

Thomas
