Just for the record, I've reconsidered and now agree with Michael that we 
should hand out /24 to ISPs who want to run 6RD, to facilitate /56 
handouts to end customers.

I would want a discussion on this being 6RD exclusive use and a 5 year 
temporary handout with option for 5 year extension per time until the 
community deems that 6RD is depreciated and this space should no longer be 
used for that.

Should we reserve a /8 for 6RD use, approximately one per ASN? Should we 
just say that a certain /8 is for 6RD use and it's not even handled by 
RIRs but instead handled like GLOP space for multicast, ie that it's just 
the ASN mapped into this space? Do we need a /6 to handle future 32bit ASN 
increase in the next 10 years?

Perhaps there should be this kind of IPv4-mapped-into-IPv6-per-ASN space 
available for general use, not being 6RD exclusive?

I do think this should be temporary though, with the aim at this being 
deprecated in 5-10 years.
