Hi,

Peter's question regarding BGP methods reminded me...

As part of the series of IPv6 multihoming meetings here this week in
Atlanta (thanks Michel and Iljitsch!), I have noted the current
and past drafts and tried to categorise them into the solutions 
spaces mentioned:

- host-based
- router based
- aggregatable pi space methods
- two-space methods

I'm reviewing these (and note an existing 12-18 month old review), but 
feel free to comment on those listed.  Note very few are active.  I'll
also post soon some summary of the discussions we've had (which focus
on a small number of the methods below, of course).
